Abstract
The present invention provides a thermal transfer image-receiving sheet which can form a clear image having a sufficiently high density and excellent in various types of fastness, particularly durability such as light fastness, fingerprint resistance and which is plasticizer resistance according to a thermal transfer printing process wherein use is made of a heat migratable dye. The thermal transfer image-receiving sheet includes 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 product of a reaction of a polyoxyalkylene polyol with an organic polyisocyanate.
