ABSTRACT:
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.
