A light-sensitive material which comprises a light-sensitive layer and a support is disclosed. The light-sensitive layer contains silver halid grains, at least two hydrazine derivatives and a polymerizable compounds. One hydrazine derivative has the following formula [I]: <IMAGE> [I] in which one of R1 and R2 is hydrogen, and the other is hydrogen, an alkylsulfonyl group, an arylsulfonyl group or an acyl group; R3 is an aliphatic group, an aromatic group or a heterocyclic group; R4 is hydrogen, an alkyl group, an aralkyl group, an aryl group, an alkoxy group, an aryloxy group, amino or carbamoyl; at least one hydrogen atom contained in R3 or R4 is replaced with a group capable of being adsorbed on silver halide grains; G is carbonyl, sulfonyl, sulfinyl, <IMAGE> (R5 has the same meanings as for R4); and each of R1, R2, R3, R4, R5 and G may have one or more substituent groups. The hydrazine derivative having the formula [I] is adsorbed on the silver halide grains in an amount of 5x10-6 to 5x10-2 mole based on 1 mole of the silver halide grains. The other hydrazine derivative functions as a reducing agent.
