    摘要： A silver halide color photographic light-sensitive material is disclosed, which is improved in the color forming efficiency, the color reproducibility and the resistivity of color image against heat and humidity. The photographic material comprises a silver halide emulsion layer which contains a pyrazoloazole type cyan coupler having a group represented by Formula I which is directly bonded to the azole ring of the pyrazoloazole coupler:--(X.dbd.Y)n--R.sub.1 (I)wherein X and Y each is a substituted or unsubstituted methine group or a nitrogen atom; R.sub.1 is a hydrogen atom or a substituent; and n is an integer of 1 or 2, provided that two of Xs and two of Ys may be the same or different from each other when n is 2, and two of either X, Y and R.sub.1 are allowed to be bonded each other to form a ring other than benzene ring.
