摘要：
A dye-forming coupler of formula (I), a silver halide photographic light-sensitive material containing the coupler, and an azomethine dye that can be derived from the dye-forming coupler: wherein Q is a group —C(—R11)═C(—R12)—SO2—; R11 and R12 bond with each other to form, together with the —C═C— moiety, a 5- to 7-membered ring, or they each represent a hydrogen atom or a substituent; R1, R3 and R4 each represent a substituent; m is an integer of 0 to 4; and X represents a hydrogen atom or a group that splits off upon a coupling reaction with an oxidized product of a developing agent; with the proviso that the following compound (I-A) is excluded from the dye-forming coupler of formula (I).
