る。Conventional Structure and Problems Conventionally, full-color thermal recording dye transfer bodies containing sublimable dyes, which can be applied to high-speed recording, have been 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.

塑化されたものが良好である。 Examples of the polyester-based polymer compound or composition used for the film substrate 2 include polyethylene terephthalate, polyethylene naphthalate, and compounds mainly composed of these. Among them, polyethylene terephthalate has excellent heat resistance and is versatile, so it is effectively used and gives excellent results. In addition, as the polyester polymer binder 6 of the coloring material layer 3, a soluble or internally plasticized binder with particularly good solubility or dispersibility is preferable.

一な昇華による良好な画質を与える。 Since these binders have good adhesion to the film substrate 2 and excellent heat resistance, they do not peel off from the film substrate 2 even when heated during recording. Moreover, sufficient recording density can be obtained due to this good adhesiveness. This is because the heat of the thermal head 1 is smoothly conducted to the polyester polymer binder 6 through the film base 2 and efficiently transferred to the sublimable dye 4 for good adhesion. be interpreted. Furthermore, since these film substrates 2 have particularly little unevenness in thickness, they provide good image quality due to uniform dye sublimation.

る。 For example, when polyethylene terephthalate is used as the film substrate 2, the film substrate 2 and the coloring material layer 3 are softened by the heat during recording and are fused to each other, so that the coloring material layer 3 is in the vicinity of the substrate 2. The dye 4 is trapped in the fused portion 7. For this reason, by including a large amount of the dye 4 in the coloring material layer 3, it becomes possible to record repeatedly many times. The dye 4' trapped in the fused portion 7 is effectively utilized in subsequent recordings performed a plurality of times. Disperse dyes that have good dispersion or compatibility with polyester polymer compounds are particularly effective in this regard.
A dye coverage of 0.2 g/m 2 or more gives good results.

It is also effective to provide a heat-resistant protective layer on the thermal head side surface 8 of the film base 2 to improve the heat resistance of the film base 2.
