The color hard copies obtained from both transfer bodies each have a characteristic color. Especially, the latter has a characteristic that it is easy to reproduce the halftone of the color and is beautiful. However, much heat energy is required to sublimate or evaporate the dye as compared with the former method. Conventionally, capacitor paper or polyester film has been mainly used as the substrate. Condenser paper has excellent heat resistance, but has uneven heat conduction due to uneven density. On the other hand, the polyester film does not have uneven density, but is inferior in heat resistance, and therefore is insufficient for use in high density printing by heating at high temperature.

出した。That is, when a polyester film is used as a sublimation dye type substrate, when heat energy for obtaining a required recording density is applied to the head, heat absorption of the polyester film itself or diffusion phenomenon of the dye into the substrate is sufficient. We have found the disadvantage that it is not possible to obtain high print density.

防ぐことができ、優れた転写体を与える。Among transfer materials for thermal recording (hereinafter abbreviated as transfer materials) used for recording by thermal transfer, a sublimation dye type transfer material in which a color material layer contains a sublimable dye requires a large amount of heat in order to sublimate or evaporate the dye. Need energy. Therefore, when a film having a low melting point and being melted or softened by the heat of the head is used for the substrate, the heat energy added to the dye sublimation or evaporation is absorbed by the substrate, or the diffusion of the dye into the softened substrate is prevented. This causes a phenomenon that the recording density is lowered. However, if a heat-resistant protective layer made of a photocurable resin is provided between the substrate and the color material layer, the above phenomenon can be prevented and an excellent transfer member can be provided.

い。For the heat-resistant protective layer, any heat-resistant material can be used as long as it does not adversely affect heat-sensitive recording. In particular, a photocurable resin having good adhesion to a substrate during recording and having a heat distortion temperature or a deflection temperature under load of 80 ° C. or higher exhibits good properties. Here, the heat distortion temperature or the deflection temperature under load is the test method of the American Society for Testing Materials (ASTM, D648, load 18.6).
It is the temperature determined by kg / cm 2 ). The photocurable resin is easily cured in a short time, and a long transfer body is easily produced.

Polypropylene-based polymers such as pre-propylene and poly-4-methylpentene; cellulose acetate-based polymers such as acetyl cellulose; polyvinylidene fluoride; fluorine-based polymers such as 4-fluoroethylene-6-fluoropropylene copolymer is there.
