KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft die Herstellung eines neutralen, gut haftenden, nicht glänzenden Fixatifs, welches aufserdem die Eigenschaft besitzt, infolge des zu seiner Herstellung verwendeten leichtflüchtigen Lösungsmittels rasch zu trocknen.The present invention relates to the production of a neutral, well-adhering, non-glossy one Fixatifs, which also has the property due to the fact that it is used for its manufacture to dry quickly with volatile solvents.
Dieses Fixatif erlaubt, Zeichnungen u. dergl., die mit Pastell, Kohle oder irgend welchen anderen Farbstoffen, mit Ausnahme von Fettstiften, auf Papier, Pauspapier, Garton, Holz, Gips oder dergl. hergestellt sind, ohne Glanz zu fixiren. Bedingung dabei ist nur, dafs das Material, auf welches die Zeichnung aufgebracht ist, genügend porös ist, um die Fixirflüssigkeit, welche darauf aufgetragen wird, zu absorbiren, event, kann das Material auch durch eine besondere Behandlung absorbirend gemacht werden.This fixation allows drawings and the like made with pastel, charcoal or whatever other dyes, with the exception of crayons, on paper, tracing paper, garton, wood, Plaster of paris or the like are made without fixing gloss. The only condition is that that The material on which the drawing is applied is sufficiently porous to which is applied to it to absorb, if necessary, the material can also be given by a special one Treatment to be made absorbent.
Da das nach vorliegendem Verfahren hergestellte Fixatif beinahe vollständig neutral ist, so besitzt es den Vortheil, weder die Pastellfarben oder dergl. noch die Farbe des Papiers, auf dem die Farben aufgetragen sind und welches das Fixirmittel aufnimmt, zu schädigen oder zu verändern.Since the fixative produced according to the present process is almost completely neutral, so it has the advantage, neither the pastel colors or the like, nor the color of the paper, on which the colors are applied and which the fixative absorbs or to change.
Das Fixatif besteht der Hauptsache nach aus einer Lösung von Casei'n in acetonfreiem Methylalkohol.The fixative mainly consists of a solution of Casei'n in acetone-free Methyl alcohol.
Die Verwendung einer alkoholischen Casei'nlösung zu dem angegebenen Zwecke war bisher nicht bekannt. Man kannte nur eine wässerige Borax-Casei'nlösung, die als Kitt und zum Erzeugen eines glänzenden Ueberzuges auf PapierThe use of an alcoholic casein solution for the stated purpose was not previously known. One only knew a watery one Borax casein solution, which is used as putty and for producing a glossy coating on paper
u. dergl. Anwendung gefunden hat (s. Lehner, Kitte und Klebemittel, 1899, S. 51).and the like. Has found application (see Lehner, Kitte und Adhesives, 1899, p. 51).
Eine derartige Lösung ist naturgemäfs als Fixatif von Zeichnungen u. dergl. nicht zu verwenden, da ein solches Fixatif zu schwer und träge wirken, die Contouren verwaschen, das Papier werfen und schwer durchdringen und schliefslich zu langsam trocknen würde.Such a solution is naturally not to be used as a fixation for drawings and the like use, because such a fixative is too heavy and sluggish, the contours are washed out, the paper would throw and hard to penetrate and eventually dry too slowly.
Das vorliegende alkoholische Fixatif beseitigt alle diese Nachtheile.The present alcoholic fixative eliminates all these disadvantages.
Dasselbe wird zweckmäfsig in folgender Weise hergestellt.The same is conveniently made in the following manner.
Um z. B. ι 1 des Fixatifs zu bereiten, bringt man ungefähr 25 g chemisch reines Casein, welches von Fett befreit ist, in 200 bis 250 g destillirtes Wasser, welches mit Borax gesättigt und auf eine Temperatur von ungefähr 40 ° C. erwärmt ist, und läfst die Mischung während einiger Tage stehen. Die Lösung vollzieht sich mehr oder minder schnell, je nach der Temperatur, welche der Raum hat, in dem man arbeitet; eine Normaltemperatur von ungefähr 20° C. hat sich als vortheilhaft erwiesen. To z. B. ι 1 of the fixative to prepare, one brings about 25 g of chemically pure casein, which has been freed from fat, in 200 to 250 g of distilled water which is saturated with borax and is heated to a temperature of about 40 ° C., and leaves the mixture during stand for a few days. The solution takes place more or less quickly, depending on the Temperature of the room in which one works; a normal temperature of approximately 20 ° C. has proven to be beneficial.
Wenn die Auflösung vollendet ist, giefst man die Lösung allmählich unter Umrühren in 750 bis 800 ecm absoluten acetonfreien Methylalkohol.When the dissolution is complete, the solution is poured in gradually while stirring in 750 to 800 ecm of absolute acetone-free methyl alcohol.
Der Lösung kann zweckmäfsig etwas Aethylalkohol bezw. Aether hinzugefügt werden.The solution can expediently bezw some ethyl alcohol. Aether to be added.
Die auf die angegebene Weise erhaltene Flüssigkeit hat alsdann ein milchiges Aussehen; nach etwa 20 tägiger Ruhe klärt sich dieThe liquid obtained in the manner indicated then has a milky appearance; after about 20 days of rest it clears up
Flüssigkeit und hinterlässt einen leichten Niederschlag. Man dekantirt alsdann, worauf die Flüssigkeit zum Gebrauch fertig ist.Liquid and leaves a slight precipitate. It is then decanted, whereupon the liquid is ready for use.
Vorliegendes Fixatif, welches in der beschriebenen Weise hergestellt ist, besitzt für die Praxis genügende Neutralität und zeigt nur eine sehr geringe Einwirkung auf Lackmus; es wird wie die gewöhnlichen Fixatifs angewendet, indem man es in feinem Staubregen mittelst irgend welchen Zerstäubers auf die Zeichnung aufträgt.The present fixative, which is manufactured in the manner described, has for the practice has sufficient neutrality and shows only a very small effect on litmus; it is applied like the ordinary fixative, by putting it in a fine rain of dust by means of some kind of atomizer on the drawing.
