| titleOfInvention | Photographic element having improved magenta dye light stability and process for its use |
| abstract | The invention provides a photographic element comprising a silvernhalide emulsion layer having associated therewith a dye-forming couplernrepresented by formula II:n nwhereinn X is hydrogen or a coupling-off group; R 1 , R 2 , and R 3 are independently selected alkyl groups, providednthat any two of R 1 , R 2, and R 3 may join to form a ring; R 4 is hydrogen or a substituent, provided that R 3 and R 4 may join tonform a ring when R 4 is a substituent; R a is hydrogen or a substituent; each Y is an independently selected substituent with at least one Ynsubstituent in the 2-position (relative to oxygen) having the formula -NHSO 2 R f ,nwherein R f is an alkyl or aryl group, and n is from 1 to 5. n The element exhibits improved magenta dye light stability. |
