A photographic light sensitive silver halide emulsion layer has associated therewith a pyrazoloazole dye-forming coupler having the formula: <IMAGE>zolotriazole nucleus by a fully substituted carbon atom; X is hydrogen or a coupling-off group; L is a divalent linking group; R2, R3, and R4 are independently hydrogen or substituent groups; and Za, Zb, and Zc are independently -C(R')(R'')-, =N-, =C(R')-, or -NH-, wherein R', and R'' are independently H or a substituent, provided that one of either the Za-Zb or the Zb-Zc bond is a double bond and the other is a single bond, and provided that when the Zb-Zc bond is a double bond, it may form part of a fused ring. |
