Photographic element, compound, and process

摘要

Disclosed is a photographic element comprising a light-sensitive silver halide emulsion layer having associated therewith a "NB coupler" having the formula (I):whereinthe 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 0 to 5 and p is 0 to 2;W2 represents the atoms necessary to complete a carbocyclic or heterocyclic ring group; andV is a substituent group containing a sulfonamido group;provided that the combined sum of the aliphatic carbon atoms in V, all Z'' and all Z* is at least 8. The element provides a dye of improved hue.
