| 摘要 |
A light-sensitive material is described, comprising a support having provided thereon a light-sensitive layer containing at least a light-sensitive silver halide, a polymerizable compound, a color image forming substance, and a hydrazine derivative represented by formula (I): <IMAGE> (I) wherein R1 represents a monovalent group derived from a substituted or unsubstituted aromatic ring or aromatic heterocyclic ring; R2 and R3 each represents a substituted or unsubstituted aryl group; and R4 represents a hydrogen atom or a substituted or unsubstituted alkyl, aryl, alkoxycarbonyl, or carbamoyl group, in which the color image forming substance is immobilized by imagewise exposure to light followed by heat development under conditions substantially not containing water. The material exhibits high sensitivity and provides a color image through a simple, easy, and rapid dry processing step, with a reduced exposure time.
