Abstract
A light-sensitive silver halide photographic material is disclosed. The light-sensitive material comprises a support having thereon a silver halide emulsion layer, and the silver halide emulsion layer comprises silver halide grains having a silver chloride content of not less than 95 mol %. The emulsion is optically sensitized by addition of a dispersion of an optical sensitizer comprising a medium and particles of the dye dispersed in the medium. The ratio of silver to gelatin (Ag/Gel) in the emulsion at the time of addition of the dispersion of the dye is 2 to 8.5.
