ABSTRACT:
An image recording process is disclosed. The process comprises the steps of: imagewise exposing silver halide to light to form a latent image of the silver halide; developing the formed latent image of the silver halide with a reducing agent; and conducting substantially uniform light exposure in the presence of a photopolymerization initiator and an ethylenically unsaturated polymerizable compound to form a polymer image. According to the present invention, the reducing agent forms an oxidation product having a function as a polymerization inhibitor after the development. Thus a polymer image is formed within the area where the oxidation product of the reducing agent has not been formed. The reducing agent has the following formula [I]: ##STR1## in which R.sup.1 is an alkyl group, an aryl group or a heterocyclic group; R.sup.2 is an organic group which is attached to the benzene ring by a hetero-atom having a lone pair of electrons; R.sup.3 is a halogen atom, an alkyl group, an aryl group or a heterocyclic group; m is 1, 2, 3 or 4; n is an integer satisfying the formula, 0.ltoreq.n.ltoreq.(4-m); and an aromatic ring, an aliphatic ring and/or a heterocyclic ring may be condensed with the benzene ring.
