THERMALLY DEVELOPABLE PHOTOSENSITIVE MATERIAL

摘要

PURPOSE:To reduce the adhesion of a thermally developable photosensitive element to a thermally developable image receiving element after thermal development and to facilitate the stripping of the photosensitive element from the image receiving element by interposing a stripping layer contg. a compound contg. F atoms between the elements. CONSTITUTION:A layer contg. a compound contg. F atoms such as a compound represented by a formula R1SO2N(R2)CH2R3 [where R1 is 40-20C alkyl having F atoms substituted for part or all of the H atoms, R2 is 1-6C alkyl or 6-10C aryl and R3 is -CO-O-(C2H4O)m- or the like] is used as a stripping layer. A layer contg. photosensitive silver halide and a dye providing substance is used as a thermally developable photosensitive element. The stripping layer is interposed between the photosensitive element and a thermally developable image receiving element to obtain a thermally developable photosensitive material. Since the stripping layer is interposed, the photosensitive element can easily be stripped from the image receiving layer after thermal development, so the commodity value can be enhanced.
