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.
