Abstract (en)

[origin: EP0435270A1] A silver halide emulsion contains light-sensitive silver halide grains in a binder. At least one oxidizing agent for silver is added after 50% of water-soluble silver chloride used in grain formation of the silver halide emulsion are added and before chemical sensitization is performed. A silver halide photographic light-sensitive material includes at least one layer of the emulsion.
