Abstract:
A photographic element comprising a light-sensitive silver halide emulsion layer having associated therewith a cyan ""NB coupler"" having the formula (I): ##STR25##wherein:the term ""NB coupler"" represents a coupler of formula (I) that forms a dye for which the left bandwidth (LBW) using spin-coating is at least 5 nm less than that of the same dye in solution form;Y is H or a coupling-off group;each Z"" and Z* is an independently selected substituent group where n is 1 to 4 and p is 0 to 2;W.sup.2 represents the atoms necessary to complete a carbocyclic or heterocyclic ring group; andV is a sulfone or sulfoxide containing group;provided that the combined sum of the aliphatic carbon atoms in V, all Z"" and all Z* is at least 8; and the sum of the aliphatic carbon atoms in all Z"" substituents combined is at least 6;provided further that when W.sup.2 forms a carbocyclic aromatic ring, at least one Z"" is selected from the group consisting of alkoxy, alkylaryl, aryloxy, carbonamido, cyano, halogen, hydroxy, nitro, oxysulfonyl, sulfoxide, thio, and ureido groups.
