Abstract
A gold-sensitized silver halide emulsion of surface latent image type exhibits improved shelf stability while maintaining high sensitivity when at least 80% of the gold sensitizer is contained in the silver halide grain phase. A photographic silver halide light-sensitive material is prepared as comprising at least one emulsion layer which contains the improved silver halide emulsion.
Claims15
A gold-sensitized silver halide emulsion substantially of surface latent image type comprising silver halide grains, a gold sensitizer, and a binder, at least 80% by weight of the gold sensitizer being present in the silver halide grain phase.
A photographic silver halide light-sensitive material comprising at least one emulsion layer which contains at least one gold-sensitized silver halide emulsion substantially of surface latent image type comprising silver halide grains, a gold sensitizer, and a binder, at least 80% by weight of the gold sensitizer being present in the silver halide grain phase.
A photographic silver halide light-sensitive material comprising at least one layer of a gold-sensitized silver halide emulsion substantially of surface latent image type, at least 80% by weight of the total amount of gold sensitizer contained in said light-sensitive material being present in the silver halide grain phase.
