Abstract (en)

[origin: EP0613044A2] 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 1x10<-><7> to 5x10<-><3> mole based on 1 mole of silver halide. A localized phase of the complex is present on the surface of the grains. 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.
