International Classification:

G03C001/46

US Classification:

430502000

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.

International Classification:

G03C 746

US Classification:

430387

Abstract:

Disclosed is a photographic element comprising a silver halide emulsion layer having associated therewith a dye-forming coupler represented by Formula I: ##STR1## wherein R" represents the group ##STR2## in which R. sup. 1, R. sup. 2, and R. sup. 3 independently selected all groups, provided that any two of R. sup. 1, R. sup. 2, and R. sup. 3 may join to form a ring; R. sup. 4 is hydrogen or a substituent, provided that R. sup. 3 and R. sup. 4 may join to form a ring when R. sup. 4 is a substituent; and W is a specified substituent having the formula: ##STR3## and wherein the remaining substituents are as described in the specification. The use of the coupler of Formula I lends improved manufacturability and dye light stability to the element.
