Abstract
A light-sensitive material comprises a light-sensitive layer which contains silver halide, a reducing agent and an ethylenic unsaturated polymerizable compound provided on a support (the silver halide and polymerizable compound are contained in microcapsules which are dispersed in the light-sensitive layer), characterized in that the microcapsules have an average particle size (volume average particle diameter) of 8.5 to 20 .mu.m and the following specific particle size distribution. The amount of the microcapsules having a particle size of not larger than one-sixth part of the average particle size is not more than 1 volume % of the total amount of the microcapsules and the amount of the microcapsules having a particle size of not smaller than twice as large as the average particle size is not more than 1 volume % of the total amount of the microcapsules. The microcapsules preferably have a proportion (a/b) of an average thickness (a) of the shell of the microcapsules to the average particles size (b) in the range of 0.5.times.10.sup.-2 to 5.times.10.sup.-2.
