ABSTRACT:
A silver halide color photographic light-sensitive material capable of providing a dye image having improved spectral absorption characteristic as well as high color-forming property and excellent dye image fastness is disclosed. The light-sensitive material comprises at least one silver halide emulsion layer having a cyan color-forming property, wherein the silver halide emulsion layer having the cyan color-forming property contains at least one cyan coupler represented by the following formula (I) or (II) and at least one of a sparingly water-soluble homopolymer and/or copolymer: ##STR1## wherein Za and Zb each represents --C(R.sub.3).dbd. or --N.dbd., provided that one of Za and Zb is --N.dbd. and the other is --C(R.sub.3).dbd.; R.sub.1 and R.sub.2 each are an electron attractive group having a Hammett's substituent constant .sigma..sub.p of 0.2 or more and the sum of the .sigma..sub.p values of R.sub.1 and R.sub.2 is 0.65 or more; R.sub.3 represents a hydrogen atom or a substituent; and X represents a hydrogen atom or a group capable of splitting off upon a reaction with an oxidation product of an aromatic primary amine color developing agent.
