Abstract
An image is formed by subjecting to imagewise exposure an image forming medium containing at least a heat-diffusible coloring matter, a photosensitive silver halide, an organic silver salt, a reducing agent, a polymerizable polymer precursor and a photopolymerization initiator; heating the image forming medium thus treated; subjecting it to polymerization exposure to form a polymerized area and an unpolymerized area in the image forming medium; separating the polymerized area from the unpolymerized area; and superposing an image receiving medium onto the unpolymerized area to transfer the heat-diffusible coloring matter in the unpolymerized area to the image receiving medium.
Claims5
A method of forming an image comprising in sequence the steps of:
- (a) securing an image receiving medium to a support member;
- (b) superposing onto said image receiving medium an image forming medium containing at least a heat-diffusible coloring matter, a polymerizable polymer precursor, a photopolymerization initiator, a photosensitive silver halide, an organic silver salt and a reducing agent for forming a light absorbing compound after (i) an oxidation-reduction reaction or (ii) upon reaction with a coupler after said oxidation-reduction reaction;
- (c) subjecting said image forming medium to imagewise exposure;
- (d) heating said image forming medium;
- (e) subjecting said image forming medium to polymerization exposure to form a polymerized area and an unpolymerized area in the image forming medium;
- (f) separating said polymerized area from said unpolymerized area to such that said unpolymerized area is arranged on said image receiving medium;
- (g) transferring said heat-diffusible coloring matter in said unpolymerized area to said image receiving medium;
- and
- (h) removing said unpolymerized area from said image receiving medium.
