Abstract
Abstract A light-sensitive material comprises a light-sensitive layer containing silver halide, a reducing agent and a polymerizable compound provided on a paper support. A surface of the paper support on which the light-sensitive layer is provided has a low water absorptiveness of not more than 3 g/m² which is a value measured according to Cobb test method.
