Abstract
A light-sensitive material comprises a support and a light-sensitive layer containing silver halide, a polymerizable compound and a hydrazine derivative. The light-sensitive layer further contains a reducing agent having the following formula (I): ##STR1## in which each of Ar.sup.1 and Ar.sup.2 independently is an aryl group; and each of R.sup.1, R.sup.2 and R.sup.3 independently is a monovalent group such as hydrogen, a halogen atom, an alkyl group, a cycloalkyl, group, an aralkyl group, an aryl group, an alkenyl group, an alkynyl group, a heterocyclic group, an alkoxy group, an alkylthio group and an acylamino group.
