Abstract:
A photographic element comprising a light sensitive silver halide emulsion layer having associated therewith an open chain a-carbonyl acetanilide yellow dye-forming coupler compound having the formula: ##STR10## wherein R.sub.1 is selected from the group consisting of alkyl, aryl, heterocyclic, and amino groups, provided that R.sub.1 may form a ring bonded to another carbon atom which is a member of Ring ""A"";each R.sub.2 is independently a substituent having a Hammett's sigma value of 0 or less, and m is from 0 to 4;each R.sub.3 and R.sub.4 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 R.sub.5 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 R.sub.5 groups may join to form a ring;R.sub.6 is a multicarbocyclic or multiheterocyclic group having a common vertex through which it is attached to the indicated carbonyl group;each L is independently a divalent linking group and q is 0 to 3;Ring ""A"" is bonded indirectly to the 3-, 4-, or 5-position of Ring ""B"", andZ is hydrogen or a group capable of coupling-off when the coupler reacts with an oxidized color developer.
