Abstract

A silver halide color photo-graphic light-sensitive material having an excellent performance in a rapid processing and color reproduction and providing a stable photographic performance against a composition change in a processing solution is disclose, which comprises a support and provided thereon a photographic constitutional layer comprising each at least one layer of 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 at least one non-light-sensitive layer, wherein the above silver halide emulsion layer containing the cyan dye-forming coupler contains (i) at least one of specific pyrroloazole cyan couplers, and (ii) (a) silver bromochloride grains having a silver chloride content of 90 mole % or more or silver chloride grains, each chemically sensitized with a gold compound or (b) silver bromochloride grains containing substantially no silver iodide and having a silver chloride content of 90 mole % or more and a silver bromide-rich phase on the grain surface or in the inside thereof having a silver bromide content larger by 5 mole % or more than those at the other portions.

A silver halide color photographic light-sensitive material comprising a support and provided thereon a photographic constitutional layer which comprises at least one layer of each of 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 at least one non-light-sensitive layer, wherein

the above silver halide emulsion layer containing a cyan dye-forming coupler contains (i) at least one of the pyrroloazole cyan couplers represented by Formula (Ia) in an amount of 1.times.10.sup.-3 to 1 mole per mole of silver halide, and (ii) silver bromochloride grains having a silver chloride content of 90 mole % or more or silver chloride grains, each chemically sensitized with a gold compound in an amount of 1.times.10.sup.'s to 1.times.10.sup.-8 mole per mole of silver halide:
##STR122## wherein Za represents --NH-- or --CH(R.sub.3)--, and Zb and Zc each represent --C(R.sub.4).dbd. or --N.dbd.;
R.sub.1, R.sub.2 and R.sub.3 each represent an electron attractive group having a Hammett's substituent constant .sigma..sub.p of 0.20 or more, provided that the sum of the .sigma..sub.p values of R.sub.1 and R.sub.2 is 0.65 or more;
R.sub.4 represents a hydrogen atom or a substituent, provided that when two R.sub.4 's 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.sub.1, R.sub.2, R.sub.3, R.sub.4 or X may become a divalent group and combine to form a dimer or a polymer higher than a dimer or bond to a high molecular chain to form a homopolymer or a copolymer, and
the whole amount of calcium contained in the photographic constitutional layer is 15 mg or less per m.sup.2 of the light-sensitive material.
