Photographic element and compound and process useful therewith

Abstract

Disclosed is a photographic element comprising a light-sensitive silver halide emulsion layer having associated therewith a bicyclic azole dye-forming coupler compound having Formula I: wherein: BA represents a bicyclic azole coupler nucleus with —(C(R1)(R2))P— bonded to a ring carbon in a non-coupling position of the coupler nucleus; p is 1 or 2, and each R1 and R2 is independently selected from H and a substituent group, provided that any two of R1 and R2 may join to form a ring; Ra and Rb are each independently selected from H and a substituent group, provided that substituent groups may join to form a ring; each Y is an independently selected substituent and m is 0-4; X is selected from the group consisting of —C(O)—, —S(O)2—, —S(O)—, and —P(O)(OH)—; W is a connecting group having a chain of up to four atoms between X and Z, and n=0 or 1; and a) when n=0, Z is —NHR5 where R5 is H or a substituent, and b) when n=1, Z is selected from —OH, —SO2NHR5, and —NHR6 where R5 is H or a substituent group and R6 is a substituent bonded to —NH— by an electron withdrawing group in R6; provided that the ClogP value of the coupler compound is at least 5.0. The element provides improved color rendition.
