The present invention relates to a polyester for thermal transfer image-receiving sheets which includes a polyester A produced from an alcohol component containing 50 mol% or more of an alkyleneoxide adduct of 2,2-bis(4-hydroxyphenyl)propane and an acid component containing 80 mol% or more of an aliphatic carboxylic acid and/or an alicyclic carboxylic acid as a total amount thereof, and a polyester B produced from an alcohol component containing 80 mol% or more of the alkyleneoxide adduct of 2,2-bis(4-hydroxyphenyl)propane and an acid component containing 10 to 35 mol% of a trivalent or higher valent aromatic polycarboxylic acid; a resin dispersion containing the polyester; a process for producing the resin dispersion; a thermal transfer image-receiving sheet using the polyester; and a process for producing the thermal transfer image-receiving sheet. The thermal transfer image-receiving sheet is capable of satisfying all of a dyeability, a light resistance and a releasability at the same time.
本发明涉及一种用于热转印图像接收片材的聚酯,其中包括一种聚酯A,由含有50 mol%或更多2,2-双(4-羟基苯基)丙烷的亚烷氧基加合物的醇组分和含有80 mol%或更多脂肪族羧酸和/或脂环族羧酸(作为其总量)的酸组分制成、一种聚酯 B,由含有 80 摩尔%或更多 2,2-双(4-羟基苯基)丙烷的亚烷氧基加合物的醇组分和含有 10 至 35 摩尔%的三价或更高价芳香族聚羧酸的酸组分制成;含有聚酯的树脂分散体;生产树脂分散体的工艺;使用聚酯的热转印图像接收片材;以及生产热转印图像接收片材的工艺。该热转印图像接收片能够同时满足染色性、耐光性和释放性的所有要求。
