ABSTRACT:
A silver halide photographic material comprises a support and a light-sensitive layer provided thereon. The light-sensitive layer contains silver halide grains dispersed in gelatin. A hexa-coordinated cyano-complex is doped in the silver halide grains. The amount of the complex is in the range of 1.times.10.sup.-7 to 5.times.10.sup.-3 mol based on 1 mol of silver halide. A localized phase of the complex is present on the surface of the grains. The localized phase contains the complex in an amount of 1.times.10.sup.-5 to 1.times.10.sup.-1 mol based on 1 mol of silver halide. According to the present invention, the silver halide grains are doped in the presence of a compound having a function of inhibiting a reaction of the cyano-complex with gelatin, or the compound having the function is added to the grains after the grains are doped.
