Dependent claims

A silver color photographic light-sensitive material comprising:

(a) a paper support;
(b) a color image-forming emulsion layer containing a photographic color coupler which forms a dye on coupling with an oxidized aromatic primary amine, said color image-forming emulsion layer comprising a blue-sensitive emulsion layer containing a yellow coupler, a green-sensitive emulsion layer containing a magneta coupler, a red-sensitive emulsion layer containing a cyan coupler, wherein said yellow coupler is selected from the group consisting of a coupler represented by the formula (IV) ##STR31## wherein Y.sub.1 represents an aliphatic group, an aromatic group or a heterocyclic group;
Y.sub.2 represents an aromatic group or a heterocyclic group;
and X represents hydrogen or a cleavable group which is capable of being cleaved as an anion during the oxidation coupling reaction with the oxidation product of the aromatic primary amine developer,
and a coupler represented by the formula (V) ##STR32## wherein Q.sub.1 represents halogen, alkoxy, aryloxy, dialkylamino or alkyl;
Q.sub.2 is positioned at 4- or 5-position of the anilido nucleus and represents halogen, trifluoromethyl, acylamino, sulfonamido, ureido, alkyl, alkoxy, aryloxy, carboxy, alkoxycarbonyl, carbamoyl, sulfo, sulfamoyl or imido;
and X represents hydrogen or a cleavable group which is capable of being cleaved as an anion during the oxidation coupling reaction with the oxidation product of the aromatic primary amine developer;
(c) an oxygen-impermeable layer having an oxygen permeability of not more than 2.0 ml/m.sup.2 ".eta..theta..multidot.atm, said oxygen-impermeable layer being located between the paper support and the color image-forming layer;
and
(d) a protective layer providing a top surface on the same side of the paper support as the color image-forming layer and the oxygen-impermeable layer, said protective layer containing gelatin as a binder having a thickness of from about 0.4 to 4 .mu.m.
