ABSTRACT:
A light-sensitive material comprises a paper support and a light-sensitive layer containing silver halide grains, a reducing agent and an ethylenic unsaturated polymerizable compound. The silver halide grains and polymerizable compound are contained in microcapsules which are dispersed in the light-sensitive layer. The light-sensitive layer has a pH value of not higher than 8. The paper support has a pH value of from 5 to 9. An image-forming method employing the light-sensitive material is also disclosed.
