Abstract
Disclosed is (1) a silver halide photographic material having at least one light-sensitive emulsion layer containing a silver halide emulsion on a support, wherein the light-sensitive emulsion layer comprises silver halide grains which contain at least one complex selected from the group consisting of Ir and Pt metal complexes having at least two cyan ligands which have a silver chloride content of 80 mol % or more and do not substantially contain silver iodide and which have a silver bromide-rich localized phase with a silver bromide content of 10 mol % or more, and (2) a silver halide photographic material having at least one light-sensitive emulsion layer containing a silver halide emulsion on a support, wherein the light-sensitive emulsion layer comprises silver halide grains which contain at least one complex selected from the group consisting of Ir and Pt metal complexes having at least two cyan ligands, which have a silver chloride content of 80 mol % or more and which are gold-sensitized.
