PHOTOTHERMOGRAPHIC MATERIAL, METHOD FOR FORMING VISIBLE IMAGE, AND INTEGRATED BODY FOR IMAGE FORMATION

PROBLEM TO BE SOLVED: To improve the picture quality of a photothermographic material. SOLUTION: The material is a black-and-white water-based photothermographic material having one or more heat developable image forming layers on a supporting body. The heat developable image forming layer contains a hydrophilic binder and a preliminarily prepared photosensitive silver halide, a nonphotosensitive reducible silver ion source as an organic silver salt except for a silver carboxylate, and a reducing agent composition for the nonphotosensitive reducible silver ion source which are combined to cause the reaction. Further, one or more layers of the heat developable image forming layers contain a specified mercapto triazole as toner described in the specification. The photothermographic material can be used for radiography by using a phosphorescence intensifying paper together. COPYRIGHT: (C)2004,JPO
