Photographic acetanilide couplers and photographic elements containing them |
| abstract |
Novel photographic acetanilide dye-forming couplers comprise a group comprising a stabilizer moiety represented by the formula: ##STR1## wherein R is halogen or alkoxy having 1 to 4 carbon atoms; R 1 is hydrogen, halogen, alkyl or alkoxy; R 2 and R 3 are individually alkyl; and, X is a linking group. Such couplers provide advantageous stability in dyes formed from the couplers. These couplers are useful in photographic silver halide materials and processes. |
