Image forming method and image forming material using it

Abstract

Abstract PURPOSE:To obtain a polymer image on an exposed area by using a compd. serviceable as the developing agent of silver halide and the polymn. inhibitor of a polymerizable vinyl monomer, and uniformly exposing a photosensitive layer to inhibit polymn. of an unexposed area after imagewise exposure and development of a latent image. CONSTITUTION:A recording material 13 is obtained by successively forming on a support 16 a photosensitive layer 15 contg. a silver halide and a compd., such ad hydroquinone or p-aminophenol, having both actions of development inhibition of polymn. of a polymerizable vinyl monomer, especially, a mixture A of 1-phenyl-3- pyrazolidone and hydroquinone, and a layer 14 contg. a photopolymerizable compsn. A silver image 18 is formed in the latent image part by imagewise exposing (A) the recording material 13 from the side of the layer 14, and heating it. The mixture A having a polymn. inhibition action is diffused from the unexposed area 15 into the layer 14. A polymer image 20 is produced by uniformly exposing (C) the material 13 entirely and photopolymerizing the part of the layer 14 corresponding to the silver image 18. The unexposed part of the layer 14 is not polymerized, thus permitting a high-quality polymer image suitable for a printing plate, etc., to be formed.
