Abstract

Abstract A light-sensitive material comprising a light-sensitive layer which contains silver halide, a reducing agent, a polymerizable compound and a color image forming substance provided on a support, wherein the silver halide, the polymerizable compound and the color image forming substance are contained in at least three kinds of microcapsules (I), (II) and (III) which are dispersed in the light-sensitive layer. Each of the microcapsules (I), (II) and (III) differs from each other with respect to the spectral sensitivity of the silver halide. The hue of the color image forming substance contained in the microcapsule (I) is the same as that in the microcapsule (II), and the hue of the color image forming substance contained in the microcapsule (III) is different from those in the microcapsules (I) and (II).
