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.

Abstract: A silver halide emulsion comprises silver halide grains having a silver chloride content of not less than 10 mol % and a silver bromide content of not less than 0.1 mol % the silver halide grains being formed in the presence of at least one of compounds represented by the following Formula I:Formula IY.sub.n1 MBr.sub.n2 X.sub.n3wherein M represents an ion selected from the group consisting of rhenium, ruthenium, osmium, platinum, palladium, and iridium ion; Y represents a cation; X represents a ligand coordinating M; n.sub.1 represents an integer of 0 to 3; and n.sub.2 and n.sub.3 each represent an integer, provided that n.sub.2 .gtoreq.n.sub.3 and n.sub.2 +n.sub.3 =4 or 6.
