Abstract

A light-sensitive silver halide grain containing at least one metal complex, wherein when an a-axis, a b-axis and a c-axis of a silver halide crystal lattice are each established taking as an origin a central metal of the metal complex incorporated into the silver halide grain, the metal complex has in a ligand thereof a site which can form any bond of a covalent bond, a dative bond and an ionic bond, or a bond in a mixed form of these bonds with a silver ion on a lattice point which does not exist on any of the a-axis, the b-axis and the c-axis. The silver halide photographic material has no reciprocity failure over a wide range of exposure illuminations without desensitization and decrease of contrast on the low intensity side.
