ABSTRACT:
A non-diffusible, yellow dye image-forming benzoylacetanilide coupler having an aryloxy coupling-off group where (a) the benzoyl group comprises a substituent R.sup.1 O-- wherein R.sup.1 is an alicyclic or aliphatic, unsubstituted or substituted, branched or unbranched hydrocarbon group; and, (b) at least one of the benzoyl group and acetanilide group comprise a substituent that comprises a branched alkyl group containing at least 4 carbon atoms wherein the alkyl chains are uninterrupted or interrupted by hetero atoms or groups, enables improved solubility in coupler solvents in a photographic material, and the yellow dyes resulting from such couplers upon oxidative coupling have improved light stability. Such couplers are advantageous in photographic silver halide elements and processes.
