Photographic material containing silver halide grains doped with hexa-coordinated
cyano-complex |
(57) 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 1×10⁻⁷ to 5×10⁻³ 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.
