Abstract
A silver halide light-sensitive material comprises a support, a hardening layer and a light-sensitive layer. The hardening layer contains an ethylenically unsaturated polymerizable compound and a hydrophobic polymer. The light-sensitive layer contains silver halide and a water-soluble polymer. The water-soluble polymer forms a water-soluble phase. The silver halide is dispersed in the water-soluble phase. The hardening layer or the light-sensitive layer contains a reducing agent. The light-sensitive layer further contains a water-insoluble polymer. The water-soluble polymer has a glass transition temperature of not higher than 0.degree. C. The water-insoluble polymer forms a water-insoluble phase. The water-insoluble phase is separated from the water-soluble phase.
