Abstract (en)

Disclosed is a silver halide photographic emulsion comprising silver halide grains and a protective-colloid-containing aqueous solution, wherein the silver halide grains are formed by adding a halogen element, after the initiation of the growth of the silver halide grains, to the protective-colloid-containing aqueous solution where the silver halide grains are being grown. The silver halide photographic emulsion can give a silver halide photographic light-sensitive materials high in sensitivity, excellent in graininess and satisfactory in preservability.
