ABSTRACT:
This invention relates to a silver halide photographic element comprising a support bearing a cyan dye image forming unit comprised of at least one red sensitive silver halide emulsion, a magenta dye image forming unit comprised of at least one green sensitive silver halide emulsion, and a yellow dye image forming unit comprised of at least one blue sensitive silver halide emulsion; wherein the at least one green sensitive silver halide emulsion comprises two absorptance peaks, the first peak being between 515 and 540 nm (short wavelength peak) and the second peak being between 565 and 590 nm, (long wavelength peak) and wherein(a) the ratio of the absorptance peak value of the short wavelength peak to the absorptance peak value of the long wavelength peak is from 0.65 to 1.55;(b) the absorptance minimum between the two absorptance peaks is between 530 and 560 nm;(c) the ratio of the absorptance value at the absorptance minimum to that of the smaller absorptance peak is 0.86 or less;(d) the ratio of the absorptance at 490 nm to that of the highest absorptance peak is 0.60 or less.
