摘要： The present invention relates to a silver halide photographic material that has at least one photographic constituent layer on a support, which photographic material is characterized in that said at least one photographic constituent layer contains a dispersion obtained by emulsifying and dispersing at least one hydrophobic, photographically useful material and at least one polymer compound that is water-insoluble but soluble in organic solvents and which has a phenolic hydroxyl group.

摘要： A silver halide photographic material having photographic constituent layers on a support, which photographic material is characterized in that at least one of said photographic constituent layers is a silver halide emulsion layer, at least 50% in number of the light-sensitive silver halide grains in said silver halide emulsion layer being grains that contain at least 60 mol % of silver bromide, and at least one of said photographic constituent layers containing at least one of the compounds represented by the following general formula (I):[HlAu.sub.m (L).sub.n (X).sub.p ].sub.q (I)where L is a 1igand in a 5- or 6-membered hetero ring; X is an anionic group; l is an integer of 0-2; m is an integer of 1 or 2; n is an integer of 1-3; p is an integer of 0-3; and q is an integer of 1-4. The silver halide photographic material has high sensitivity and yet it is improved in protection against deterioration in its photographic performance such as increased fog and degraded granularity due to storage after manufacture.
