Abstract
Abstract There is disclosed a silver halide color photo-graphic light-sensitive material capable of providing a dye image having excellent color reproducibility, sharpness and image fastness. The light-sensitive material comprises a support having provided thereon a photographic constituent layer comprising a light-sensitive silver halide emulsion layer containing a yellow dye-forming coupler, a light-sensitive silver halide emulsion layer containing a magenta dye-forming coupler, and a light-sensitive silver halide emulsion layer containing a cyan dye-forming coupler, and non-light-sensitive hydrophilic colloid layers. The above silver halide emulsion layer containing the cyan dye-forming coupler contains at least one cyan dye-forming couplers represented by the following Formula (Ia), and wherein at least one of the non-light-sensitive hydrophilic colloid layers is provided between the support and the silver halide emulsion layer closest to the support and contains a white pigment in a filling rate of 20 weight % or more: ##STR1## wherein Za represents --NH-- or --CH(R 3 )--, and Zb and Zc each represents --C(R 4 )═ or --N═; R 1 , R 2 and R 3 each represents an electron attractive group having a Hammett's substituent constant σ p of 0.20 or more, provided that the sum of the σ p values of R 1 and R 2 is 0.65 or more; R 4 represents a hydrogen atom or a substituent, provided that when two R 4 groups are present in the formula, they may be the same or different; 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; the group represented by R 1 , R 2 , R 3 , R 4 or X may become a divalent group and combine with a polymer higher than a dimer and a high molecular chain to form a homopolymer or a copolymer.
