Description

  The present invention relates to a decorative body having a special visual effect using a microlens.

  Conventionally, patterns using moire have been used as building materials and decoration materials. The most rudimentary moire pattern is obtained by overlapping two identical screens and rotating one screen. By applying this principle, the shape and angle of the pattern as the unit of the pattern. By changing variously, it is possible to create an infinite variety of patterns.

  On the other hand, there is known a decorative material that exhibits a special visual effect by using a microlens sheet in which microlenses that are fine convex lenses are regularly arranged on the surface of a transparent synthetic resin plate. The microlens sheet is an expensive sheet because it is a sheet manufactured by forming fine irregularities on the surface of a thermoplastic resin sheet using a precise mold. The decorative sheet described in Patent Document 1 is provided with a plurality of convex lens-shaped protrusions in a continuous pattern on the surface of a transparent sheet and a pattern having the same continuous pattern as the surface on the back surface of the sheet. It is a decorative sheet printed by being displaced with respect to a pattern.

  Attempts have also been made to form microlenses by printing rather than molding. The dot-drawn pattern decorative body described in Patent Document 2 is a regular arrangement of a large number of independent convex condensing elements having transparency on a surface of a transparent substrate by a printing ink having transparency at a constant fine pitch. A large number of colored pixels are printed on the back surface of the transparent substrate in the same shape as the convex condensing elements on the front surface or in the same arrangement state or in different shapes and the same arrangement state. The positional relationship is shifted with respect to the convex condensing element on the surface so that the size changes greatly, and the colored pixels appear as an enlarged image with a stereoscopic effect when viewed from the surface, and the viewpoint is moved. And an enlarged image of a point drawing pattern characterized in that the enlarged image exhibits a sense of fluctuation.

  This decorative object is a three-dimensional dot drawing pattern that uses the phenomenon that the amplitude increases or decreases when the crossing angle is shifted by overlapping regular patterns like halftone dots, and the dots appear to fluctuate. It is a decorative body that has appeared.

  The three-dimensional pattern decorative body described in Patent Document 3 is provided with a plurality of layers or a single layer in a predetermined pattern continuously with a dot-like pattern colored in a desired color on the surface of a transparent or opaque decorative body, A transparent dot-shaped convex lens having a substantially hemispherical cross section is continuously attached to the surface of the decorative body and each pattern in the same pattern as the above pattern, and a moire pattern appears on each pattern and each convex lens pattern. The pattern and the convex lens are arranged so as to gradually become dense toward the dense area set on the surface of the decorative body, and are arranged in a rough area set in a portion far from the dense area. It is a three-dimensional pattern decorative body arranged in a gradation that gradually becomes rough toward. This decorative body can three-dimensionally display a gradation moire pattern having a dense area and a rough area.

  The decorative body described in Patent Document 4 includes a pixel layer formed by aligning a plurality of pixels on a reflective layer, and a plano-convex lens layer formed by aligning a plurality of plano-convex lenses. It is a decorative body in which an image appears by changing the arrangement of pixels in various ways.

The decorative body described in Patent Document 5 is a letter-like shape drawn at a pitch B using a visual expression pattern provided in a dot pattern at a pitch A on a base material and a varnish having liquid repellency on the visual expression pattern surface. A liquid repellent pattern provided on the liquid repellent pattern, and a microlens formed on the extracted character portion by applying a transparent varnish on the liquid repellent pattern, and the pitch A and the pitch B are set to different pitches for visual expression. A decorative body in which a pattern in which a dot pattern of an image is enlarged appears at an equal pitch so that it can be viewed three-dimensionally, and a reflective layer is provided between the base material and the visual expression pattern. is there.

Japanese Patent No.2761861 Japanese Patent No. 3338860 JP 2005-193501 A JP 2009-262374 JP 2011-005685 JP

  The decorative sheet described in Patent Document 1 must be expensive because a lens sheet using a mold is used. Moreover, as long as a lens sheet using a mold is used, it is not impossible to realize a design in which the effects of the lens are partially arranged, but it is more difficult in terms of cost.

  Since the decorative body of the point drawing pattern described in Patent Document 2 and the three-dimensional pattern decorative body described in Patent Document 3 both form lenses by printing means, it is not possible to use expensive molds. However, since a screen printing method that relatively easily deposits ink is used as a means for forming lenses, there is a limit to accurately forming and arranging fine lenses over a large area. The screen printing method is slow in printing speed and is not suitable for mass production.

  In addition, since any of the above decorative bodies realizes the generation of a moire pattern by a method of changing the angle of one pattern, the generated moire pattern itself is accompanied by some angle and gives a controlled and neat impression. It cannot be said to be a thing.

  In the decorative body described in Patent Document 4, as a method of changing the arrangement of pixels with respect to the arrangement of plano-convex lenses, a method of changing only the arrangement pitch without changing the angle is described. Accordingly, the above-described problem does not occur, and the moire pattern gives a controlled impression. However, since the decorative body described in Patent Document 4 always needs to correspond to each plano-convex lens, the reflection layer is a metal reflection layer over the entire surface, or positioned under each convex lens. It is necessary to put together. Moreover, since thick printing by the screen printing method is used as the lens forming means, it has the same problems as in Patent Documents 2 and 3.

  When the reflective layer is provided on the entire surface, for example, it is not possible to realize a decorative body through which the inside using a transparent base material can be seen through. On the other hand, if the reflective layer can be aligned with each convex lens, this problem can be solved. However, it is practical to provide the reflective layer, the pixel layer, and the plano-convex lens layer on the substrate while accurately aligning the three layers. Even if possible, even if possible, if a general pattern other than pixels is inserted under the lens layer, the dot pattern included in the pattern will interfere with the lens, causing unintended moire or interference. Since a pattern is generated, a pattern other than a dedicated pixel cannot be arranged under the lens layer.

In the decorative body described in Patent Document 5 filed by the present applicant, in the arrangement of the visual expression pattern and the microlens, the angle is not changed but only the pitch is changed. It maintains the same directionality as the expression pattern and microlens pattern, and gives a well-controlled impression. However, since the decorative body described in Patent Document 5 is provided with a reflective layer over the entire surface of the base material, it cannot be applied to a transparent base material, and when a general pattern is provided, In some cases, the halftone dots interfere with the microlens and cause unintended moire or interference fringes.

  The problem to be solved by the present invention is a decorative body having a three-dimensional visual effect that causes an interference pattern to appear between the microlens and the pixel arrangement pattern. It is to provide a microlens decorative body that does not express a pattern.

As a means for solving the above-mentioned problems, the invention according to claim 1 is characterized in that a reflective pattern layer provided on the same plane in a dot pattern with a pitch A on a substrate, and a liquid repellency on the reflective pattern layer A liquid repellent pattern formed in a letter shape using pitch varnish using a varnish having a property, and a microlens formed on the liquid letter portion by applying a transparent varnish on the liquid repellent pattern, the pitch A And a pitch B different from each other, a pattern in which the dot pattern of the reflective pattern layer is enlarged is displayed at an equal pitch so that it can be viewed three-dimensionally. A microlens decorative body provided with a pattern layer composed of dots.

  The invention according to claim 2 is the microlens decorative body according to claim 1, further comprising a transparent layer between the reflective pattern layer and the liquid repellent pattern.

The invention according to claim 3 is the microlens decorative body according to claim 1 or 2, wherein the reflective pattern layer is a metal vapor deposition layer .

The invention according to claim 4 is the microlens decorative body according to claim 1 or 2, wherein the reflective pattern layer is an ink layer containing glitter particles.

  The microlens decorative body according to the present invention is a pattern in which the dot pattern of the reflective pattern layer is enlarged by changing the pitch of the reflective pattern layer and the microlens provided in a dot pattern on the substrate (hereinafter abbreviated as an enlarged pattern). Therefore, the enlarged pattern maintains the same directionality as that of the reflective pattern and the microlens pattern, and gives a tightly controlled impression. In addition, since the generated enlarged pattern appears to move as the viewpoint moves, a three-dimensional feeling is expressed.

  In addition, the microlens decorative body according to the present invention is different from the configuration in which the conventional reflective layer is provided on the entire surface, and since the reflective layer is provided in a dot pattern, by selecting a transparent material as a base material, It can be set as the decorative body which can be seen through.

The microlens decorative body according to the present invention has a reflective pattern layer provided in a dot pattern at a pitch A on a substrate and a microlens formed at a pitch B, and the pitch A and the pitch B are set to different pitches. This is a decorative body in which the dot pattern of the reflective pattern layer is enlarged and appears in a uniform pitch so that it can be viewed three-dimensionally. The layer and the reflective pattern layer, or the pattern layer and the microlens do not produce an unintended interference pattern, and a stable quality product can be obtained.

  Since a general pattern composed of halftone dots can be used in combination, the decorative body can be used widely for various purposes.

  The microlens decorative body according to the present invention uses a method of forming a microlens by applying a transparent varnish on a liquid-repellent pattern provided in a letter shape with a pitch B and bounce it. Therefore, it is possible to use an offset printing method or a gravure printing method as a printing method of the liquid repellent pattern. For this reason, a high-definition and finely detailed expression that is difficult to realize by the screen printing method is possible.

  When a transparent layer is provided between the reflective pattern layer and the liquid repellent pattern, the enlarged pattern formed by the reflective pattern layer and the microlens is enhanced more three-dimensionally.

  When the reflective pattern layer is a metal partial vapor deposition layer or formed by transferring a metal vapor deposition transfer foil, a reflective pattern layer having strong specular reflectivity can be obtained. The output will be emphasized. On the other hand, when the reflective pattern layer is formed by printing ink containing glittering particles, the appearance of the enlarged pattern is weaker than when the metal vapor-deposited transfer foil is used. Since the process can be completed in a normal printing machine, a low-cost product can be efficiently produced.

FIG. 6 is a schematic cross-sectional view showing a cross-sectional structure of another embodiment of the microlens decorative body according to the present invention. FIG. 7 is a schematic cross-sectional view showing a cross-sectional structure of another embodiment of the microlens decorative body according to the present invention.

  Hereinafter, a microlens decorative body according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic cross-sectional view showing a cross-sectional structure of an embodiment of a microlens decorative body according to the present invention. FIG. 2 is a schematic plan view showing a planar structure of the microlens decorative body shown in FIG.

  The microlens decorative body according to the present invention has a pitch B using a reflective pattern layer (2) provided in a dot pattern with a pitch A on a substrate (1) and a varnish having liquid repellency on the reflective pattern layer. A liquid repellent pattern (3) provided in the shape of a cut-out character and a microlens (5) formed in the cut-out character portion by applying a transparent varnish on the liquid-repellent pattern, and the pitch A and pitch B are A pattern in which the dot pattern of the reflective pattern layer (2) is enlarged at different pitches to appear in a three-dimensional manner by providing different pitches, and is above or below the reflective pattern layer (2). A microlens decorative body provided with an arbitrary picture layer (4) composed of halftone dots

  In FIG. 1, (7) indicates the pitch (A) of the reflective pattern, and (8) indicates the microlens pitch (B). Note that the character pitch of the liquid repellent pattern is equal to the pitch of the microlenses. In this example, the pitch B is larger than the pitch A, but conversely, the pitch A may be larger than the pitch B. In the embodiment shown in FIG. 1, the picture layer (4) is under the reflective pattern layer (2). In FIG. 1, the picture layer (4) is drawn as a single layer for the sake of convenience. However, as shown in FIG. 2, the picture layer (4) is actually composed of halftone dots. Therefore, it is not necessarily a continuous single layer.

  FIG. 3 is an enlarged plan view illustrating a mechanism in which an enlarged pattern is generated in the microlens decorative body according to the present invention. FIG. 4 is an enlarged plan view illustrating a mechanism in which an enlarged pattern is generated in the microlens decorative body according to the present invention, in which the enlargement magnification is lower than that in FIG. In this embodiment, the reflective pattern (2) is a circular dot, and is arranged in a regular triangle shape with a constant reflective pattern pitch (A) (7). A liquid repellent pattern (3) formed from above using liquid repellent ink is provided. The liquid repellent pattern (3) is a negative pattern of circular dots arranged in an equilateral triangle shape with a constant microlens pitch (B) (8), that is, a letter shape, and is formed on the liquid repellent pattern (3). The applied transparent varnish is repelled and gathers in a circular dot portion, which is a letter to be removed, to form a microlens (5). The size of the microlens (5) is suitably about 0.05 mm to 0.5 mm in diameter.

  When the reflective pattern pitch (A) (7) and the microlens pitch (B) (8) are set to different values, the positions of the dots on the reflective pattern layer (2) and the microlens (5) gradually shift, Attempts to match again at a position shifted by one pitch. In the portion where both coincide, the center portion of the dots of the reflective pattern layer (2) is enlarged by the microlens (5), and in the portion where they do not coincide, the middle portion of the dots of the reflective pattern layer (2) becomes the microlens ( Enlarged in 5). In this way, the dot portion of the reflective pattern layer (2) to be enlarged moves gradually shifted and returns to the original position at a position shifted by one pitch. As a result of repeated matching and non-matching of the pitch, when viewed with the naked eye, it is recognized as if the dots of the reflective pattern layer (2) were enlarged. The values of the reflective pattern pitch (7) and the microlens pitch (8) are preferably about 0.05 mm to 1.0 mm.

  FIG. 4 is an enlarged plan view illustrating a mechanism in which an enlarged pattern is generated in the decorative body according to the present invention, in which the enlargement magnification is lower than that in FIG. As can be seen from the figure, the region (9) in which the central part of the dots of the reflective pattern layer (2) is enlarged and the region (10) in which the middle part of the dots of the reflective pattern layer (2) is enlarged are periodic. Appear at regular intervals. This appears as an enlarged pattern and is recognized by the naked eye.

  As the substrate (1), a substrate of any material such as paper, a synthetic resin film, a synthetic resin plate can be used, but the present invention is capable of forming a fine microlens accurately even with a large-area substrate. In order to make use of the above characteristics, paper or paperboard, synthetic resin film, synthetic resin sheet, PET bonding paper (film bonding paper) or the like to which the offset printing method or gravure rotary printing method can be applied are desirable. Note that printing by a screen printing method may be applied using a plate material such as cardboard or a synthetic resin plate as a base material. In addition, as a feature of the present invention, a transparent base material can be used to make a decorative body that can be seen through.

  The reflective pattern layer (2) is a layer having a property of reflecting light formed in a dot pattern at a constant pitch (A), and the shape of the dot pattern is arbitrary. In the example of FIG. 2, the dot pattern has a square shape, and in the example of FIG. 3, it has a circular shape.

  There are several methods for forming the reflective pattern layer (2). The first is a method using a partial vapor deposition method. After applying a ground treatment such as a vapor deposition anchor coat to a water-resistant plastic film such as a PET film, aluminum is vapor-deposited on the entire surface, and then this aluminum vapor deposition is performed. A protective varnish is printed on the surface in a pattern to be the reflective pattern layer (2). Subsequently, it is treated with a dilute alkaline solution to dissolve and remove the unnecessary vapor deposition film, so that the portion of the vapor deposition layer where the protective varnish exists remains and the reflective pattern layer (2) is obtained. The water-resistant plastic film may be used as the substrate (1) as it is, or may be bonded to another substrate, for example, paperboard, as the substrate (1).

  As another method for forming the reflective pattern layer (2), similarly, after applying a ground treatment such as a vapor deposition anchor coat to a water-resistant plastic film as necessary, a reflective pattern layer ( The negative pattern of 2) is printed, and then aluminum is vapor-deposited on the entire surface, followed by washing with water to remove the vapor-deposited layer of the water-soluble varnish portion, whereby the desired reflective pattern layer (2) is obtained. This method is also generally classified as a partial vapor deposition method. Similarly, the water-resistant plastic film may be used as it is as the base material (1), or may be bonded to another base material such as paperboard as the base material (1).

As another method for forming the reflective pattern layer (2), there is a method using a metal vapor-deposited transfer foil.
For example, a vapor deposition transfer layer having a layer structure such as a peeling varnish / metal vapor deposition layer / adhesion varnish is provided in advance on a base film such as a PET film, and this vapor deposition transfer layer is used as a reflective pattern layer (2 ) To obtain only the reflective pattern layer (2).

  There are also several methods for partially transferring the vapor deposition transfer layer of the metal vapor deposition transfer foil to the substrate. The simplest method is to transfer by heating with a hot plate or a hot roll in which the pattern of the desired reflective pattern layer (2) is formed as a convex portion on the surface. This method is a method called foil stamping, which has been generally performed as a decorative method. However, in order to synchronize the reflective pattern layer (2) and the pattern layer (4), a printing press is used. It is necessary to install a special transfer device to synchronize with the printing plate.

  As another method of partially transferring the vapor-deposited transfer layer of the metal vapor-deposited transfer foil to the base material, an adhesive is printed on the surface of the base material (1) in a pattern corresponding to the reflective pattern layer (2). There is a method in which a metal vapor-deposited transfer foil is bonded in an uncured state, and the adhesive is cured together with the foil attached on the adhesive after peeling off the transfer foil.

  In this method, since the pattern of the reflective pattern layer (2) can be formed by printing, the synchronization with the pattern layer (4) and the liquid repellent pattern (3), which are other printed patterns, is relatively easy in terms of accuracy. It is also an advantageous method in that it is easily possible.

  When the pattern of the reflective pattern layer (2) is formed using an adhesive, in order to synchronize with the other printed pattern by in-line printing, the adhesive needs to be cured to some extent rapidly. Examples of such adhesives include dry laminate type adhesives, hot melt type adhesives, and ionizing radiation curable adhesives.

Among ionizing radiation curable adhesives, when using an electron beam curable adhesive, the metal deposition layer of the transfer foil is not significantly affected, but in the case of an ultraviolet curable adhesive, If the metal vapor deposition layer is too thick, ultraviolet rays do not pass therethrough and there is a risk of causing poor curing.

  Use a transfer foil that is thin enough to allow ultraviolet light to pass through the metal vapor-deposited layer of the metal vapor-deposited transfer foil. After printing and forming an ultraviolet-curing adhesive, the transfer foil is overlaid, and the transfer foil is peeled off and pasted on the adhesive. The method of transferring the film by irradiating it with ultraviolet rays from the attached foil can be preferably used because the equipment cost is low compared with the case of using an electron beam.

  As another method of forming the reflective pattern layer (2), there is a method of forming the reflective pattern layer (2) by printing ink containing glittering particles. As the ink containing the glitter particles, metallic ink containing the glitter aluminum flakes and pearl ink containing the glitter pearl pigment can be used. As a printing method, a general printing method such as a gravure printing method, an offset printing method, or a screen printing method can be used.

  According to the method for forming the reflective pattern layer (2) by printing ink containing glittering particles, the pattern layer (4), the liquid repellent pattern (3), etc., which are other printed patterns, are simultaneously formed on one unit. Since it is possible to easily perform in-line printing by a printing machine, it is advantageous in terms of productivity and production cost.

  The liquid repellent pattern (3) is formed in a letter shape using ink having liquid repellency. As the liquid-repellent ink, inks obtained by adding a small amount of silicone oil or silicone resin to normally used inks or varnishes, or inks using silicone resins or fluorine-based resins as binders can be used. Usually, the liquid-repellent pattern is generally colorless and transparent, but may be appropriately colored in order to obtain a design effect. The shape of the liquid repellent pattern (3) is arbitrary, such as a polka dot negative arranged in an equilateral triangle shape as shown in FIG. 3, a polka dot negative arranged in a square shape, a grid pattern, or a honeycomb shape. .

  When a transparent varnish is applied to the surface of the liquid-repellent pattern (3) and repelled along the liquid-repellent pattern, the transparent varnish gathers in the extracted character portion of the liquid-repellent pattern and rises to a convex shape, thereby Form. The transparent varnish is preferably a resin composition with good transparency that does not contain a filler such as a matting agent and has a high solid content. An ultraviolet curable transparent gloss varnish having a solid content of 100% can be preferably used.

  FIG. 5 is a schematic cross-sectional view showing a cross-sectional structure of another embodiment of the microlens decorative body according to the present invention. In this embodiment, the pattern layer (4) is present on the reflective pattern layer (2). Since the pattern layer (4) is composed of halftone dots, the pattern layer (4) is formed on the reflective pattern layer (2) unless the pattern uses a high dot area ratio and high concealment ink. It doesn't matter if you get on.

FIG. 6 is a schematic cross-sectional view showing a cross-sectional structure of another embodiment of the microlens decorative body according to the present invention. In this embodiment, the picture layer (4) and the reflective pattern layer (2) are laminated in this order on the substrate (1), and the transparent layer (6) is provided over the entire surface. .
Due to the presence of the transparent layer (6), light incident from the microlens (5) is reflected by the reflective pattern layer (2), and the optical path length when the light is emitted again through the microlens (5) is long. Therefore, the enlarged pattern of the reflective pattern that is the interference pattern appears more emphasized.

  The transparent layer (6) may be a transparent varnish layer or may be formed by laminating a transparent film. When a partially vapor-deposited film as already described is used as the reflective pattern layer (2), the base film of the vapor-deposited film can be used as the transparent layer (6).

FIG. 7 is a schematic cross-sectional view showing a cross-sectional structure of another embodiment of the microlens decorative body according to the present invention. In this embodiment, the reflective pattern layer (2) with the transparent layer (6) is disposed on the pattern layer (4) provided on the surface of the substrate (1). Such a configuration can be formed by a partial transfer method using a metal vapor-deposited transfer foil having a release varnish layer in the reflective pattern layer (2) formation method already described. In this case, the peeling varnish layer of the transfer foil functions as the transparent layer (6). In this case, if the transparent layer (6) is colored and transparent, for example, gold or any other color metallic expression can be easily realized.

  As another method for realizing a microlens decorative body having a structure as shown in FIG. 7, a transparent layer (6) is formed on a partially provided reflective pattern layer (2) while being aligned by a printing method. There is also a method of providing.

Since the transparent layer (6) is colored and transparent, the structure as shown in FIG. 7 has an adverse effect on the design layer (4) in design and is not preferable. It can be particularly preferably used in some cases.
Hereinafter, the microlens decorative body according to the present invention will be described more specifically based on examples.

  A card paper having a basis weight of 310 g was used as a base material, and a pattern layer, a reflective pattern layer, and a liquid repellent pattern were printed on the surface in this order by an offset printing method. The pattern layer was a 175 line 100% flat screen ink pattern. The reflective pattern layer was a circular dot having a dot diameter of 0.2 mm, and the reflective pattern pitch was 0.31 mm.

  The reflective pattern layer was formed using an inline foil stamping device installed in an offset printing machine. A UV curable adhesive is printed on the dot pattern of the reflective pattern layer, and a cold foil for inline foil pressing is bonded from above, and after the transfer foil is peeled off, UV light is irradiated through the transferred foil by a UV lamp, The adhesive was cured to obtain a reflective pattern layer.

  The liquid repellent pattern was printed using a repellent ink in which silicone oil was added to the ink medium. The diameter of the polka dots to be the microlens was 0.3 mm, and the pitch was 0.33 mm. From this, an ultraviolet curable transparent gloss varnish was applied to the entire surface, and the liquid-repellent pattern portion was bounced, and then irradiated with ultraviolet rays to form a microlens to obtain a target microlens decorative body.

  A microlens decorative body was produced in the same manner as in Example 1 except that the design of the picture layer was a 175 line 60% flat mesh ink pattern.

  The specification of the pattern layer is that of Example 1 except that a 175 line flat net 60% red pattern and a transparent blue varnish layer having a thickness of 0.005 mm or less is provided as a transparent layer only on the reflective pattern layer. Similarly, a microlens decorative body was produced.

  The specification of the pattern layer is the same as that of Example 1 except that a 175-line flat 100% black ink pattern, a transparent layer on the reflective pattern layer, and a transparent varnish layer having a thickness of 0.3 mm are provided on the entire surface. Thus, a microlens decorative body was produced.

<Comparative Example 1>
As a substrate, a paperboard laminated with an aluminum foil on the entire surface was used, and a microlens decorative body having a layer structure of a picture layer, a pixel layer, and a microlens was produced. The pattern layer was white 175 line flat mesh 100%, and the pixel layer was a black dot pattern with a dot diameter of 0.2 mm and a dot pitch of 0.31 mm. The specifications of the microlens are the same as those in the first to fourth embodiments.

<Comparative Example 2>
A microlens decorative body was produced in the same manner as in Comparative Example 1 except that the pattern layer was red with a 175 line flat mesh of 60%.
Table 1 shows the results of visual evaluation of the appearances of Examples 1 to 4 and Comparative Examples 1 and 2.

  As described above, the microlens decorative body according to the present invention inserts a normal shaded pattern without generating unintended moire or the like in an enlarged pattern area expressed by the microlens and the reflective pattern. Became possible. For this reason, it can be used in a wide range as a surface decoration material for boxes and containers for storing various articles.
