Abstract: A light-sensitive material comprises a light-sensitive layer containing a light-sensitive silver halide, a reducing agent and a polymerizable compound having an ethylenic unsaturated group which is provided on a support. The light-sensitive layer contains a polymer binder having an ethylenic unsaturated double bonding group in its side chain. The light-sensitive material is advantageously employable as a lithographic plate.

Abstract: A method for recording a photographic image on an image-recording material is provided, wherein an image-recording material formed by coating at least a photographic silver halide, a polymerizable vinyl monomer, and a hydrazine derivative represented by formula (I) ##STR1## wherein X represents a hydrogen atom, an alkyl group, or a group represented by ##STR2## positioned in an ortho-, meta-, or para-position on the benzene ring; Y represents ##STR3## or --SO.sub.2 --; R.sub.1, R.sub.2, R.sub.3, and R.sub.4 each represents a hydrogen atom, an unsubstituted alkyl group, or a substituted alkyl group, provided that R.sub.1 represents a hydrogen atom only when Y represents ##STR4## on a support is imagewise exposed to form a latent image in said photographic silver halide and then heated so as to polymerize said polymerizable vinyl monomer in the part having said latent image to form a polymer image therein.

Abstract: An image forming method is disclosed, comprising forming a latent image by imagewise exposing a recording material including a light-sensitive silver salt, a reducing agent, a polymerizable compound, and a binder, on a support, and subsequently subjecting said recording material to a substantially uniform heating at about 80.degree. C. or more under conditions substantially not containing water, thereby forming a polymeric compound in areas where the latent image of the light-sensitive silver salt has formed.
