| titleOfInvention | Photographic elements with improved magenta dye light stability |
| abstract | (57) [Problem] To provide a photographic element further improved in dye light stability. A photographic element having a silver halide emulsion layer containing a coupler of the following formula: [X is hydrogen or a coupling-off group, and R 1 , R 2 and R 3 are independently selected from alkyl groups, Any two of R 1 , R 2 , and R 3 can combine to form a ring, and R 4 is hydrogen or a substituent, but when R 4 is a substituent, R 3 and R 4 can combine to form a ring, R a is hydrogen or a substituent, and each Y is Independently selected substituent, 2-position (relative to oxygen) At least one Y substituent has the formula —NHSO 2 R f , where R f is an alkyl or aryl group, and n is 1-5. |
