Abstract
Disclosed is a photographic element comprising a light-sensitive silver halide emulsion layer having associated therewith a cyan dye-forming coupler represented by Formula (I): wherein: each R1 and R3 is an independently selected substituent, m is 0 to 5, and p is 0 to 2; X is hydrogen or a coupling-off group; W and W2 represent the atoms necessary to complete rings; and R2 is an alkyl or aryl group. The element provides desirable hue properties and ease of synthesis.
