Photographic element having improved magenta dye light stability and process for its use

摘要

The invention provides a photographic element comprising a silver halide emulsion layer having associated therewith a dye-forming coupler represented by formula II: wherein X is hydrogen or a coupling-off group; R1, R2, and R3 are independently selected alkyl groups, provided that any two of R1, R2 and R3 may join to form a ring; R4 is hydrogen or a substituent, provided that R3 and R4 may join to form a ring when R4 is a substituent; Ra is hydrogen or a substituent; each Y is an independently selected substituent with at least one Y substituent in the 2-position (relative to oxygen) having the formula -NHSO2Rf, wherein Rf is an alkyl or aryl group, and n is from 1 to 5. The element exhibits improved magenta dye light stability.
