Thermal transfer sheet and thermal transfer recording method

摘要

The present invention relates to thermal transfer recording technique in which a thermal transfer sheet containing a dye is heated according to image signals. There is provided a thermal transfer sheet with laminated in this order an ink layer containing a dye, a dye-diffusion preventive layer composed of an aqueous material and a particle-transfer layer composed of a softening transfer-material and dye acceptor particles of a dyeable thermoplastic resin dispersed therein. Also disclosed is a thermal transfer recording method in which the softening transfer-material is softened according to image signals so that the softening transfer-material and dye acceptor particles are dyed with the dye contained in the ink layer, whereupon image transfer to an image receiving medium can take place.
