ABSTRACT:
A light-sensitive material comprising a light-sensitive layer containing silver halide, a hydrophilic polymer adsorbed on the silver halide, a reducing agent and a polymerizable compound provided on a support, characterized in that the hydrophilic polymer comprises gelatin and a water soluble vinyl polymer having a high physical retardance is disclosed. The ratio of the vinyl polymer to the gelatin ranges from 0.1 to 20 weight %. The physical retardance of the vinyl polymer is not less than 25.0, which is defined as a value measured according to PAGI method.
