Abstract

Multilayer color photographic element having on a support base blue-, green- and red-sensitive silver halide emulsion layers respectively associated with non-diffusing yellow, magenta and cyan dye-forming couplers, wherein (a) the green-sensitive silver halide emulsion layer comprises three green-sensitive silver halide emulsion layers, respectively uppermost, intermediate and lowermost, sensitive to the same spectral region of visible light, in which the sensitivity of the three green-sensitive silver halide emulsion layers decreases in order from the uppermost silver halide emulsion layer to the lowermost silver halide emulsion layer, (b) each of the three green-sensitive silver halide emulsion layers contains an 1-phenyl-3-anilino-4-phenylthio-5-pyrazolone magenta dye-forming coupler, (c) the weight ratio of the coupler to silver halide (expressed as silver) in the highest sensitivity uppermost green-sensitive silver halide emulsion layer is higher than the weight ratio of the coupler to silver halide (expressed as silver) in the medium sensitivity intermediate green-sensitive silver halide emulsion layer, and (d) the highest sensitivity uppermost green-sensitive silver halide emulsion layer contains a DIR coupler. The color photographic elements containing the aforesaid layer arrangement provide good speed-granularity relationship, good interimage effects, and less changes in the photographic properties such as decrease in color density and increase in fog when brought in contact with formaldehyde gas during storage prior to color development.
