Abstract
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 developing agent, a polymerizable compound, a color image forming substance, and a hydrazine derivative represented by at least one of the following formula (I) and a hydrazine derivative represented by the following formula (II), in which said color image forming substance is immobilized by imagewise exposure to light, followed by heat development under conditions substantially not containing water: ##STR1## wherein R.sub.1 represents a substituted or unsubstituted alkyl, aralkyl, aryl, alkenyl, alkynyl, or heterocyclic group; and R.sub.2 represents a hydrogen atom or a substituted or unsubstituted alkyl, cycloalkyl, aralkyl, aryl, alkenyl, alkynyl, heterocyclic, alkoxy, aryloxy, alkylthio, arylthio, or amino group; ##STR2## wherein R.sub.3 represents a monovalent group derived from a substituted or unsubstituted aromatic ring or aromatic heterocyclic ring; R.sub.4 and R.sub.5 each represents a substituted or unsubstituted aryl group; and R.sub.6 represents a hydrogen atom or a substituted or unsubstituted alkyl, aryl, alkoxycarbonyl or carbamoyl group. The material exhibits high sensitivity and provides a color image through a simple, easy, and rapid dry processing step, with reduced exposure time.
