PURPOSE:To obtain the titled material capable of dry-processing with simplicity and rapidly and capable of forming a colored image having a high sensitivity by a short exposure time by mounting a photosensitive layer composed of a photosensitive silver halide and a specific compd. on a substrate body. CONSTITUTION:The titled material is formed by mounting the photosensitive layer contg. at least photosensitive silver halide, a developer, a polymerizable compd., a color image forming substance and hydrazine derivatives shown by formula I and/or II on the substrate body, and is formed so as to make the color image forming substance an immobile state by heat-processing the image, after exposing it. In the formula, R1 is a substd. or an unsubstd. alkyl or cycloalkyl group, R2 and R6 are each hydrogen atom or a substd. or an unsubstd. alkyl group, R3 is a monovalent group derivated from a substd. or an unsubstd. aromatic ring or aromatic heterocyclic ring, R4 and R5 are each a substd. or an unsubstd. aryl group. Thus, the titled material capable of dry- processing with simplicity and rapidity and capable of forming the color image having the high sensitivity by the short exposure period, is obtd. |
