Light-sensitive material

A light-sensitive material 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) ##STR9## wherein R.sub.1 represents a monovalent group derived from a substituted or unsubstituted aromatic ring or aromatic heterocyclic ring;

• R.sub.2 and R.sub.3 each represents a substituted or unsubstituted aryl group;
• and R.sub.4 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, whereby the color image forming substance is immobilized through polymerization or cross-linking of the polymerizable compound, under conditions substantially not containing water, wherein said silver halide forms a latent image upon exposure to light, and thus formed latent image acts as a catalyst to cause an oxidation-reduction between the silver halide and said hydrazine derivative.
