Photographic element, compound, and process
Disclosed is a photographic element comprising a light-sensitive silver halide emulsion layer having associated therewith a “NB coupler” having the formula (I):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 5nm less than that of the same dye in solution form;Y is H or a coupling-off group;each Z* is an independently selected substituent group where p is 0 to 2;V is a substituent group containing a sulfone group;R4is represented by the formulawherein each of R5, R6and R7is hydrogen or an independently selected substituent with no more than one being hydrogen;, provided that two or more of R5, R6and R7may join to form a ring or rings and provided that the combined sum of the aliphatic carbon atoms in V, R4and all Z* is at least 8, and provided further that R4is not a fully fluorinated alkyl group. Such elements provide improved hue.
