PURPOSE:To enable to transfer multiple times and reduce lowering of reflection density of a dye, by a method wherein a thermoplastic resin is used as a recording medium in transfer-type thermal recording, and a mixture of a dye and a resin material is used as a recording sheet. CONSTITUTION:The transfer-type thermal recording sheet 4 consists of a backing material such as a high polymer film or a condenser paper coated with a resin material 6 in which a dye 5 is dispersed. For example, a dispersible sublimable dye or a cationic sublimable dye is used as the dye 5. A water-soluble resin such as polyvinyl alcohol or polyvinyl pyrrolidone or an oleic resin such as polymethyl methacrylate is used as the resin material 6, in which case, a plasticizer or a surface active agent may be added into the resin. The transfer-type thermal recording medium 7 consists of a thermoplastic resin such as polyvinyl chloride or polystyrene or a paper, plastic or the like coated with a thermoplastic resin. Recording is performed by dissolving the dye contained in the sheet 4 into the surface of the resin material of the medium 7. |
