摘要： The invention provides a photographic element and process of forming an image where the element is a multicolor photographic element comprising at least one light sensitive photographic silver halide emulsion layer sensitive to blue light and containing a yellow image dye-forming coupler, at least one light sensitive photographic silver halide emulsion layer sensitive to green light: and containing a magenta image dye-forming coupler, and at least one light sensitive photographic silver halide emulsion layer sensitive to red light and containing a cyan dye-forming coupler,wherein the yellow image dye-forming coupler has the formula I: ##STR1## wherein t-Bu is a tertiary butyl group, Ph is an unsubstituted phenyl ring or one containing up to 5 substituents, and Y is a heterocyclic ring, substituted or non, which is capable of leaving upon reaction if the coupler with oxidized developer; andwherein said at least one light sensitive photographic silver halide emulsion layer sensitive to blue light and containing the yellow image dye-forming coupler, or another light sensitive photographic silver halide emulsion layer sensitive to blue light and containing a yellow image dye-forming coupler has associated therewith a magenta image dye-forming coupler.
