PURPOSE: To provide the silver halide photographic sensitive material which is high in sensitivity, is small in sensitivity difference between low illuminance and high illuminance and is ameliorated in reciprocity law failure.

CONSTITUTION: This photographic material has silver halide emulsion layers on a base and is constituted by incorporating novel silver halide particles into the emulsion layers. The above-mentioned silver halicle particles are chemically sensitized in the presence of a hexacoordination cyanocomplex, by which the hexacoordination cyanocomplex ions are incorporated into the particle surfaces. The amt. of the gelatin to be incorporated into the emulsion is preferably ≤15g/ silver mol. The chemical sensitization by the addition of a gold salt compd. is preferably executed.
