Abstract: A photographic element comprising a light-sensitive silver halide emulsion layer containing a 1H-pyrazolo[1,5-b][1,2,4]triazole coupler represented by structure (I): wherein R1, R2, and R3 are independently selected unsubstituted alkyl groups comprising of 3 or less carbons with the proviso that one or more of the R1, R2, and R3 groups can be joined to form a ring; R is a straight, cyclic or branched aliphatic carbon chain group and contains at least 9 aliphatic carbon atoms; each R? is an independently selected alkyl or halogen substituent, n is 0 to 3, and R?, when present, does not include an R? in the ring position between the pyrazolotriazole nucleus and the sulfonamide; and X is hydrogen or halogen.

Abstract: Disclosed is photographic element comprising a light-sensitive silver halide emulsion layer containing a 1H-pyrazolo[1,5-b][1,2,4]triazole containing in the 6-position a fully substituted methyl group, in the 7-position a hydrogen atom or halogen atom, and in the 2-position a phenyl group substituted in the meta position with a sulfonamide group free of amide, sulfonamide, ureido or ester groups and bearing at least 9 (cyclo)aliphatic carbon atoms. The element exhibits improved resistance to coupler crystallization.
