Abstract
A silver halide light-sensitive material comprising a support having provided thereon at least one silver halide emulsion layer is disclosed. The emulsion layer contains a silver halide prepared in the presence of a tetrasubstituted thiourea as a silver halide solvent and was hardened with a hardener containing a vinylsulfonyl group. Combined use of the tetrasubstituted thiourea and the hardener of the above-described kinds increases the storability of the light-sensitive material.
