ABSTRACT:
A silver halide photographic light-sensitive material having on a support at least one layer containing a color coupler selected from the compounds represented by the general formulae (III) and (IV). The coupler is dispersed using a high boiling point organic solvent selected from the compounds represented by the general formulae (I) and (II). By the combined use of such a color coupler and high boiling point organic solvent, it is possible to prevent color deepening which occurs with the lapse of time, and prevent the formation of dye stain in an area not to be developed during the development process. ##STR1## wherein R.sub.1 is an alkyl group, an alkoxy group, an acyloxy group, an aryloxy group or a halogen atom; R.sub.2 is a cyclic saturated hydrocarbon residue; m is 0 or an integer of 1 to 5; and n is an integer of 1 to 6; and wherein when m or n is an integer of 2 or more, each R.sub.1 and R.sub.2 may be the same or different. ##STR2## wherein R.sub.3 is a cyclic saturated hydrocarbon residue; and R.sub.4 and R.sub.5, which may be the same or different, each is a cyclic saturated hydrocarbon residue, an alkyl group or an aryl group. ##STR3## wherein R.sub.6 is an alkyl group containing 1 to 10 carbon atoms, which may be substituted with a phenyl group; R.sub.7 is an alkyl group containing 1 to 12 carbon atoms, which may be substituted with an alkoxy group, an alkylsulfonamido group or an alkylsulfonyl group; R.sub.8 is a chlorine atom or a methoxy group; R.sub.9 is an alkyl group containing 10 to 20 total carbon atoms, which may be substituted with an alkoxy group, a phenoxy group, an alkoxycarbonyl group or an alkylsulfonamido group; and R.sub.10 is hydrogen, a methyl group or a methoxy group. ##STR4## wherein R.sub.11 is a chlorine atom or a methoxy group; R.sub.12 is an alkyl group containing 10 to 20 total carbon atoms, which may be substituted with an alkoxy group, a phenoxy group, an alkylcarbonyl group or an alkylsulfonamido group; and X is a 2,4-dioxo-5,5-dimethyl-3-oxazolydinyl group or a group having the formula ##STR5## (wherein R.sub.13 is an alkyl group containing 1 to 10 carbon atoms, which may be substituted with a phenyl group; and R.sub.14 is an alkyl group containing 1 to 10 carbon atoms, which may be substituted with an alkoxy group, an alkylsulfonamido group or an alkylsulfonyl group).
