A silver halide photographic emulsion.

摘要

A silver halide photographic emulsion containing silver halide grains having a silver chloride content of not less than 90 mol% and a method for preparing thereof are disclosed, wherein the silver halide grains are obtained by forming said silver halide grains in the presence of a water-soluble iridium compound and a nitrogen-containing heterocyclic compound capable of forming sparingly-soluble silver salt; and by controlling the addition of said iridium compound, whereby the photographic emulsion is improved in the dependence of gradation on exposure intensity.
