    • The present invention provides a thermal transfer image-receiving sheet which can form an image excellent in the coloring density, sharpness and various types of fastness, particularly durability such as light fastness, fingerprint resistance and plasticizer resistance according to a thermal transfer printing process wherein use is made of a sublimable dye, and can be easily produced by conventional coating equipment through the use of a non-halogenated hydrocarbon solvent, such as a ketone solvent, a toluene solvent or a mixture thereof.A first embodiment of the invention is directed to a thermal transfer image-receiving sheet including a substrate sheet and a dye-receiving layer formed on at least one surface of the substrate sheet, wherein the dye-receiving layer includes a random copolycarbonate resin having structural units represented by the following general formulae (1) and (2), the molar ratio of the structural unit represented by the general formula (1) to the structural unit represented by the general formula (2) being 30:70 to 70:30 ##STR1## wherein R.sup.1 to R.sup.8 stand for hydrogen, a halogen or an alkyl group having 1 to 4 carbon atoms, A stands for a straight-chain, branched or cyclic alkylidene group having 1 to 10 carbon atoms, an aryl-substituted alkylidene group, an aryl group or a sulfonyl group and B stands for an oxygen atom or a sulfur atom.The second invention is directed to a thermal transfer image-receiving sheet comprising a substrate sheet and a dye-receiving layer formed on at least one surface of the substrate sheet, wherein said dye-receiving layer comprises at least a polycarbonate resin and an aromatic polyester resin.
    • 本发明提供一种热转印图像接收片材,其可以根据热转印印刷方法形成着色密度,清晰度和各种类型的牢度,特别是耐光性,耐指纹性和耐增塑剂性的耐久性,其中使用 由可升华的染料制成,并且可以通过使用非卤代烃溶剂如酮溶剂,甲苯溶剂或其混合物通过常规涂布设备容易地制备。 本发明的第一个实施方案涉及一种热转印图像接收片,其包括形成在基片的至少一个表面上的基片和染料接收层,其中染料接受层包括具有结构的无规共聚碳酸酯树脂 由通式(1)和(2)表示的单元由通式(1)表示的结构单元与由通式(2)表示的结构单元的摩尔比为30:70至70:30 (1)其中R1至R8代表氢,卤素或具有1至4个碳原子的烷基,A表示具有1至10个直链,支链或环状的亚烷基 碳原子,芳基取代的亚烷基,芳基或磺酰基,B代表氧原子或硫原子。 第二发明涉及一种热转印图像接收片,其包括形成在基片的至少一个表面上的基片和染料接收层,其中所述染料接收层至少包含聚碳酸酯树脂和芳族聚酯 树脂。
