ABSTRACT:
The invention provides a photographic element comprising a support bearing a blue-light sensitive silver halide emulsion layer containing an acylacetanilide yellow image dye-forming coupler having formula I or II: ##STR1## wherein: R.sub.a is a substituted or unsubstituted alkyl, alkoxy, or aryloxy group;
R.sub.b is a substituted or unsubstituted alkyl or aryl group;
R.sub.c is hydrogen or a substituted or unsubstituted alkyl group;
R.sub.1 is a substituent;
n is an integer from 0 to 2;
R.sub.2 is selected from the group consisting of halogen, trifluoromethyl, and substituted or unsubstituted alkoxy and aryloxy;
R.sub.3 is a substituted or unsubstituted alkyl group;
R.sub.4 is hydrogen, halogen, alkoxy carbonyl (--CO.sub.2 R), carbamoyl (--CONRR'), carbonamido (--NRCOR'), sulfonamido (--NRSO.sub.2 R') or trifluoromethyl; R.sub.1 is a substituent;
X is hydrogen or a coupling-off group;
wherein said blue-light sensitive silver halide emulsion layer is a low-chloride silver halide emulsion.
The invention enables improved image quality through increased interimage effects.
