摘要:
Silver halide photographic element comprising a support having coated thereon red-, green- and blue-sensitive silver halide emulsion layers comprising, respectively, cyan, magenta and yellow dye-forming couplers, wherein the blue-sensitive emulsion layer comprises at least two blue-sensitive emulsion layers, the uppermost of which has the highest-sensitivity and the lowermost of which has the lowest sensitivity, characterized in that the uppermost highest sensitivity blue-sensitive silver halide emulsion layer comprises a yellow dye-forming coupler and a cyan dye-forming coupler.
