    • A silver halide photographic negative has a red sensitive layer containing a coupler which reacts with oxidized color developer to form a cyan dye, a blue sensitive layer containing a coupler which reacts with oxidized color developer to form a yellow dye, and a green sensitive layer containing a coupler which reacts with oxidized color developer to form a magenta dye. The coupler in the green sensitive layer produces a magenta dye which has relatively low density in the 560-590 nm range as compared with magenta dyes produced by pyrazolotriazole type couplers or 1-phenyl-3-acylamino-5-pyrazolone couplers. The element additionally has an inert dye present, preferably positioned below the green sensitive layer containing the foregoing coupler. The inert dye has a peak absorption between 560-590 nm so that the negative has a ratio of density at 580 nm to density at 550 nm, both as measured at neutral midscale exposure, which is greater than exhibited by the element absent the inert dye.

    • The invention provides a silver halide color negative photographic element comprising a red sensitive silver halide emulsion layer containing a coupler which reacts with oxidized color developer to form a cyan dye, a blue sensitive silver halide emulsion layer containing a coupler which reacts with oxidized color developer to form a yellow dye, and a green sensitive silver halide emulsion layer containing a coupler which upon reaction with oxidized color developer forms a magenta image dye, the element additionally comprising a hue correction coupler associated with a green sensitive layer which coupler reacts with oxidized developer to form a magenta dye having a peak absorption between 565-600 nm so that the element has a D580/D550 ratio which is greater than that exhibited by the element absent the hue correction coupler. The invention also provides a process for forming an image in the element described.
