摘要:
A multicolor photographic element comprising a support bearing a cyan dye image-forming unit comprising at least one red-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, a magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith at least one magenta dye-forming coupler, a yellow dye image-forming unit comprising at least one blue-sensitive silver halide emulsion layer having associated therewith at least one yellow dye-forming coupler, wherein at least one of said emulsion layers comprises tabular grains having {111} major faces containing greater than 50 mole percent bromide, and accounting for greater than 50 percent total grain projected area precipitated in a peptizer that is a water dispersible cationic starch, and contains a fragmentable electron donating sensitizer.
