ABSTRACT:
A light-sensitive material comprises a support and a light-sensitive layer which contains silver halide, a reducing agent and an ethylenic unsaturated polymerizable compound. The silver halide and the polymerizable compound are contained in microcapsules which are dispersed in the light-sensitive layer. According to the present invention, the light-sensitive layer further contains silver halide which is arranged outside of the microcapsules. It is preferred that the sensitivity of the silver halide arranged outside of the microcapsules is higher than the sensitivity of the silver halide contained in the microcapsules. The difference between the two silver halides in the sensitivity preferably is not less than 0.3 in terms of log E.
