良好な画質をもつ記録が得られない場合がある。Conventional structure and its problems The 2-base type conventional structure can be applied to high-speed recording. Full-color thermal recording transfer bodies containing sublimable dyes are widely used. However, in general, recording using sublimable dyes requires a large amount of recording energy to obtain sufficient recording density, and when the sublimable dyes are bound to the base of the transfer medium with a binder, recording Due to the heat of the process, the dye may be transferred together with the binder, making it impossible to obtain a record with good image quality.

P Has excellent heat resistance and gives good results. Examples of the cellulose-based polymer binder 6 in the coloring material layer 3 include acetyl cellulose and nitrocellulose having a degree of acetylation or nitrification [f] with a degree of fragility of 1. Since these binders have good adhesion to the film base 2 and excellent heat resistance, they do not peel off from the film base 2 even when heated during recording. 1. Due to this good adhesion, sufficient recording density can be obtained. This is because the heat from the thermal head 1 is smoothly conducted to the cellulose polymer binder 6 through the entire film base 2 and efficiently transferred to the sublimable dye 4 for good adhesion. be interpreted.
さらに、これらのフィルム基体２はとくに厚みのむらが
