Field of the Invention The present invention relates to a heat-sensitive transfer recording medium set, and more particularly to a heat-sensitive transfer recording medium set having excellent scratch resistance and solvent resistance and capable of obtaining a high-resolution printed image.

れている。2. Description of the Related Art A heat-sensitive transfer recording medium having a heat-meltable ink layer on a heat-resistant substrate is used, and a receiving paper is superposed on the surface of the heat-meltable ink layer and heated by a thermal head from the side of the substrate. By doing so, a heat-sensitive transfer recording method is known in which the heat-meltable ink at the heating portion is melted and transferred to the receiving paper.

る（特開平２−１４７２９１号）。Then, in order to improve the scratch resistance of the printed image obtained by such a method, the content of the wax component in the heat-meltable ink layer is kept low, while the transferability is lowered. To prevent this, a heat-sensitive transfer recording medium set has been proposed in which a release layer is provided between a base material and a heat-meltable ink layer, and an overcoat layer is further provided on a receiving paper (JP-A-2-147291).

してかえってきたなくなるという問題がある。However, when printing is performed by a thermal transfer printer or the like using the thermal transfer recording medium set having the above-mentioned release layer and overcoat layer, the "tail" due to softening of the overcoat layer is generated. Frequently, "bleeding" and "print crushing" are observed, and in place of them, the scratch resistance and solvent resistance of the printed image are poor, or the resolution of the printed image is low. In order to prevent the softening of the overcoat layer, it is possible to put a filler such as a pigment in the overcoat layer. However, when the heat-meltable ink layer contains a resin as a main component like the above thermal transfer recording medium, There is a problem that the resolution of the printed image is reduced and it does not come back.

提供することにより、上記課題を達成するものである。The present invention provides a thermal transfer recording medium in which a release layer and a thermosoftening ink layer are sequentially laminated on a heat resistant substrate, and an overcoat layer made of a thermoplastic resin on the substrate. In a heat-sensitive transfer recording medium set in which a heat-softenable ink layer and an overcoat layer are laminated so as to face each other, the overcoat layer has a diameter of 0.01 to 1.0 μm. The above object is achieved by providing a material having holes.

は好ましくない。When the diameter of the continuous pores of the overcoat layer of the receiving medium is less than 0.01 μ, the effect of providing the continuous pores is small, while when the diameter exceeds 1.0 μ, the surface of the receiving medium becomes rough. As a result, the printed image becomes worse. Further, when the pores are not continuous pores but cell-like independent pores, there is little effect of preventing "tailing", "crushing" and the like of printing. The continuous pores should remain in the overcoat layer of the receiving medium, and when the continuous pores reach the base material, the tensile strength of the base material is significantly reduced. Further, the number of continuous pores on the surface of the overcoat layer is determined by the size of the pores, but the number that damages the printed image is not preferable.

う問題が生ずる。As a means for improving the scratch resistance and solvent resistance of a printed image by thermal transfer, there is a method of increasing the cohesive force of the transferred ink. For that purpose, a resin having an extremely large molecular weight may be used for the thermosoftening ink layer of the thermal transfer recording medium. However, when this method is used, the transfer sensitivity of the ink is lowered, so that the printed image becomes unclear.

熱転写記録媒体セットである。Therefore, an overcoat layer (thermosensitive adhesive layer) made of a thermoplastic resin is provided on the surface of the receiving medium, and an image is printed on the overcoat layer, so that the transferred ink layer has a cohesive force. It was found that the sharpness of the printed image can be maintained without lowering the transfer sensitivity even if an extremely large resin is used. This is utilized in the thermal transfer recording medium set described in JP-A-2-147291.

For this overcoat layer, almost the same type of resin as that used in the thermal transfer recording medium set described in the above publication can be used, but even when a resin having a low glass transition temperature (Tg) is used in order to increase printing sensitivity. In addition, since there are continuous pores, it is possible to obtain a clear print without causing "tail tail" or "crush" of the print.
