Transfer recording medium comprising a layer changing its transferability when provided with light and heat

摘要

A transfer recording medium comprises a support and a transfer recording layer formed thereon capable of changing its transferability when provided with light energy and heat energy. The transfer recording layer comprises at least a colorant, a binder component an a functional component sensitive to the provision of light energy and heat energy. The functional component comprises at least a photo-initiator and a polymerizing component selected from the group consisting of monomers, oligomers and prepolymers each having an unsaturated double bond. The binder component comprises a thermoplastic polymer having a glass transition temperature of 30 DEG C. or higher and a weight-average molecular weight of 5x104 or larger. The thermoplastic polymer is contained in a proportion of 5-70 wt. % of the transfer recording layer. Because of the inclusion of the polymer binder component, the transfer recording layer has an increased sensitivity contrast to illumination between under heating and under no heating.
