本発明は熱転写による記録に用いられる感熱記録用転写

濃度プリントに用いるＫは不十分である。Conventional Structures and Problems Typical types of transfer bodies for thermal recording are the wax method, in which the coloring material layer is made of a heat-melting material, and the sublimation dye method, in which the coloring material layer contains a sublimable dye. There is a transcript. The color tocovies obtained from both transfer bodies each have their own special characteristics, but the latter is particularly distinctive in that it is easy to reproduce halftones of color and is beautiful. However, compared to the former method, a large amount of thermal energy is required to sublimate or evaporate the dye. 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, although polyester film has no density unevenness, it has poor heat resistance, so K used for high density printing by high temperature heating is insufficient.

出した。In other words, when a polyester film is used as the substrate for a sublimation dye method, when heat energy is applied to the head to obtain the required recording density, the heat absorption by the polyester film itself or the diffusion phenomenon of the dye into the substrate is sufficient. We discovered that the drawback is that it is not possible to obtain a high print density.
発明の目的
本発明は、上記のような従来の欠点を解消し、耐熱性足

感熱記録用転写体を提供することを目的とする。OBJECTS OF THE INVENTION It is an object of the present invention to provide a transfer member for thermal recording which eliminates the above-mentioned conventional drawbacks and which does not cause a decrease in print density even when a substrate with poor heat resistance is used.

、優れた転写体を与える。Among thermal recording transfer bodies (hereinafter referred to as transfer bodies) used for thermal transfer recording, sublimation dye transfer bodies in which the color material layer contains a sublimable dye require a large amount of heat to sublimate or evaporate the dye. Requires energy. Therefore, if a film with a low melting point and melted or softened by the heat of the head is used as a substrate, the thermal energy applied to sublimate or evaporate the dye is absorbed by the substrate, or 1, the dye is transferred into the softened substrate. Diffusion occurs, resulting in a decrease in recording density. However, if a heat-resistant protective layer is provided between the substrate and the coloring material layer, the above phenomenon can be prevented and an excellent transfer body can be obtained.

変形温度あるいは荷重たわみ温度は、アメリカ材料試験
協会の試験方法（ＡＳＴＭ、Ｄ６４８ 、荷重１Ｂ 、

In particular, a curable resin that has good adhesion to the substrate during recording and has a heat deformation temperature or load deflection temperature of 80° C. or higher exhibits good characteristics. Here, the heat distortion temperature or the deflection temperature under load is determined by the American Society for Testing and Materials test method (ASTM, D648, load 1B,
