ABSTRACT:
In a heat-transfer image-receiving element adapted to have a superposed relation, at least during a heat-transfer processing, with a heat-transfer element containing a heat-transferable dye donator, wherein said heat-transfer image-receiving element comprises at least one of compounds having the following general Formula (I), (II) or (III) and at least one of compounds having the following general Formula (IV) ##STR1## wherein R.sub.1, R.sub.1 ', R.sub.3, R.sub.3 ' and R.sub.5 each is a hydrogen atom, alkyl, alkenyl, cycloalkyl, phenyl, naphthyl, heterocyclic, acyl, alkylsulfonyl, arylsulfonyl or aralkylsulfonyl group; R.sub.2, R.sub.4, R.sub.4 ', R.sub.6 and R.sub.7 each is a hydrogen atom, a halogen atom, or a monovalent organic group, l is an integer of from 1 to 4, q is an integer of from 1 to 6, m, n and p each is an integer of from 1 to 3, provided if the l, m, n, p and q each is an integer of not less than 2, the R.sub.2, R.sub.4, R.sub.4 ', R.sub.6 and R.sub.7 are allowed to be either the same as or different from one another; R.sub.8, R.sub.9 and R.sub.10 each is a hydrogen atom, a halogen atom, alkyl, alkenyl, cycloalkyl, phenyl, naphthyl, heterocyclic, acyl, amino, alkylsulfonyl, arylsulfonyl or aralkylsulfonyl group, and a, b and c each is an integer of from 1 to 4, R.sub.8, R.sub.9 and R.sub.10 are allowed to be either the same as or different from one another. The heat-transfer image receiving element renders a dye image formed in the color heat-diffusion transfer process stable particularly under a light irradiation condition and excellent in stability against discoloration by light and heat.
