PROBLEM TO BE SOLVED: To improve the resistance such as light resistance, finger print proofness and antiplasticity of a heat transfer image and thereby, make these properties equal to or higher than those of a silver salt photograph by adding blocked isocyanate to a dye image receiving layer before the formation of the heat transfer image. SOLUTION: A dye receptive dye image receiving layer is formed on a sheet- like base. The dye image receiving layer is formed by adding blocked isocyanate expressed by formula (in the formula, R is an alkyl group and BL is a reaction inhibitory group). Thus it is possible to significantly improve the resistance such as light resistance, finger print proofness and antiplasticity of a heat transfer image and at the same time make these properties well comparable to those of a silver salt photograph. |
