titleOfInvention | Photographic element containing yellow dye-forming coupler comprising a dye light stability enhancing ballast and process |
abstract | A photographic element comprises a light sensitive silver halide emulsion layer having associated therewith an open chain alpha -carbonyl acetanilide yellow dye-forming coupler having the formula: <IMAGE> wherein R1 is selected from the group consisting of alkyl, aryl, heterocyclic, and amino groups, provided that R1 may form a ring bonded to another carbon atom which is a member of Ring "A"; each R2 is independently selected from the group consisting of those substituents having a Hammett's sigma value of 0 or less, and m is from 0 to 4; each R3 and R4 for each of the n carbon atoms is independently selected from the group consisting of hydrogen, alkoxy, aryl, heterocyclic, aryloxy, and alkyl groups, and n is 0 to 16; each R5 is independently selected from the group consisting of amino, alkyl groups, and groups linked to the "B" ring by oxygen or sulfur, and p is 1 to 3, provided that two R5 groups may join to form a ring; each L is independently a divalent linking group and q is 0 to 3; and Ring "A" is bonded indirectly to the 3-, 4-, or 5-position of Ring "B", R6 is selected from the group consisting of alkyl, aryl, and amino groups; and Z is hydrogen, or a group capable of coupling-off when the coupler reacts with an oxidized color developing agent. |
