ABSTRACT:
The present invention relates to an image recording process which comprises a step of (i) imagewise exposing a layer containing at least silver halide of an image recording material comprising (a) silver halide, (b) a reducing agent capable of developing silver halide, (c) a photopolymerization sensitizing dye capable of being reduced into a leuco substance by said reducing agent, and (d) a polymerizable vinyl monomer, to light to form a latent image, a step of (ii) uniformly heating said recording material to form a photopolymerization sensitizing dye image in a part corresponding to said latent image, and thereafter a step of (iii) uniformly exposing a layer containing at least said formed photopolymerization sensitizing dye image and said polymerizable vinyl monomer to light to form a polymer image in the part where said photopolymerization sensitizing dye image is present, by photopolymerization. By this process, polymer images formed by photopolymerization can be obtained even if the exposure amount is low, and the polymer image can be obtained by dry processing at a low exposure amount.
