Receiving-layer-forming resin for use in thermal-transfer image-receiving sheet and thermal-transfer image-receiving sheet using such a resin

摘要

The present invention relates to a receiving-layer-forming polyester resin for use in a thermal-transfer image-receiving sheet, comprising: not less than 70 mol % of isophthalic acid and not more than 30 mol % of terephthalic acid as acid components; and not less than 30 mol % of diols having an alicyclic structure and not more than 30 mol % of ethylene glycol as diol components, and a thermal-transfer image-receiving sheet with a receiving layer formed on at least one of surfaces of the substrate sheet, in which the receiving layer is formed by such a receiving-layer-forming polyester resin.
