Abstract
In an ink composition comprising a phosphoric ester and a dye, if the phosphoric ester is composed of an acid-type phosphoric ester and a neutralized-type phosphoric ester, the phosphoric ester and the dye hardly react with each other. Therefore, when such an ink composition is used to form a dye layer, a constituent layer of a heat transfer printing sheet, the discoloration or fading of the dye layer is minimized. Further, a heat transfer printing sheet comprising a dye layer formed by using this ink composition shows improved separability from an image-receiving sheet after an image is thermally transferred to the image-receiving sheet, regardless of the material for the substrate of the image-receiving sheet. It is thus possible to obtain an excellent image on an image-receiving sheet.
