Abstract:
A photographic element comprising a light-sensitive silver halide emulsion layer having associated therewith a bicyclic azole dye-forming coupler compound having Formula I: ##STR165##wherein:BA represents a bicyclic azole coupler nucleus with --(C(R.sup.1)(R.sup.2)).sub.P -- bonded to a ring carbon in a non-coupling position of the coupler nucleus;p is 1 or 2, and each R.sup.1 and R.sup.2 is independently selected from H and a substituent group, provided that any two of R.sup.1 and R.sup.2 may join to form a ring;R.sup.a and R.sup.b 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).sub.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; anda) when n=0, Z is --NHR.sup.5 where R.sup.5 is H or a substituent, andb) when n=1, Z is selected from --OH, --S(O).sub.2 NHR.sup.5, and --NHR.sup.6where R.sup.5 is H or a substituent group and R.sup.6 is a substituent bonded to--NH-- by an electron withdrawing group in R.sup.6 ;provided that the ClogP value of the coupler compound is at least 5.0.
