PURPOSE:To enhance light fastness by forming a release layer containing a stabilizer of a dye to the surface of a dye receiving layer. CONSTITUTION:A release layer containing a stabilizer of a dye is formed to the surface of a dye receiving layer. As a resin for forming the dye receiving layer, a polyolefin resin, a halogenated polymer, a vinyl polymer, a polyester resin, a polystyrene resin, a polyamide resin, a copolymer resin of olefin and other vinyl monomer, a cellulose resin or polycarbonate are designated. As a release agent, silicone oil, a phosphate ester surfactant, a fluorine type surfactant are designated and, as the stabilizer, an oxidation inhibitor, an ultraviolet absorber and a light stabilizer are designated. The release layer is obtained by dissolving the release agent, the stabilizer and a binder in an org. solvent or dispersing them in an org. solvent or water to prepare a solution or dispersion and applying said solution or dispersion to the receiving layer by a film forming means and drying the coating layer. By this method, an image excellent in light fastness and discoloration/fading resistance can be obtained. |
