Photographic element containing magenta coupler having improved manufacturability and dye light stability

摘要

Disclosed is a photographic element comprising a silver halide emulsion layer having associated therewith a dye-forming coupler represented by Formula I: wherein R'' represents the group in which R1, R2, and R3 independently selected all 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; and W is a specified substituent having the formula: and wherein the remaining substituents are as described in the specification. The use of the coupler of Formula I lends improved manufacturability and dye light stability to the element.
