Abstract
A photographic light-sensitive material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, characterized in that the emulsion layer contains silver chlorobromide prepared in such a manner that silver halide regular crystal grains, having no twinning crystal plane and containing 50 mol % or more of silver chloride, are used as host grains, an organic compound is adsorbed on a surface of each of the host grains, and sulfur-plus-gold sensitization is performed, either during or after halide conversion in the presence of a bromide.
