PURPOSE:To obtain the titled recording member having high fixing sensitivity and capable of forming a clear image by adding a cobalt ammine complex to a photosensitive composition consisting of a color coupler, a photooxidizing agent, a redox couple, etc. and using a thermosetting resin as a binder. CONSTITUTION:The acidic salt (a) of leucoaminotriarylmethane and a strong acid as a color coupler, hexaarylbiimidazole (b) as a photooxidizing agent for the leucoaminotriarylmethane, a redox couple (c) consisting of quinone showing absorption in about 400-550nm and a hydrogen doner, a cobalt ammine complex (d) such as haxamminecobalt (III) perchlorate, and a thermosetting resin (e) such as phenol resin or epoxy regin as a binder are blended, dissolved in an org. solvent, and coated onto a support to form an about 5-20mu thick photosensitive heat-sensitive layer. Thus, the titled recording member is obtd. |
