Abstract
The invention provides a multicolor negative photographic element comprising a support bearing at least two green light sensitive silver halide emulsion layers of differing light sensitivity, the least and only the least sensitive layer containing a 1-phenyl-3-acylamino-4-nitrogenheterocycle-pyrazolin-5-one dye forming hue correction coupler which reacts with oxidized developer during development to form a dye having a D580/D550 ratio greater than that exhibited by the element absent the hue correction coupler. The invention also provides an imaging process.

A multicolor negative photographic element comprising a support bearing a cyan dye image-forming unit comprised of 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, and 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 the magenta dye image-forming unit comprises at least two green light sensitive silver halide emulsion layers of differing light sensitivity, the least and only the least green sensitive layer containing a 1-phenyl-3-acylamino-4-nitrogenheterocyclic-pyrazolin-5-one dye forming hue correction coupler which reacts with oxidized developer during development to form a dye having a maximum absorbance less than 560 nm and a D580/D550 ratio greater than that exhibited by the element absent the hue correction coupler.
