Abstract

A silver halide color photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer, wherein in at least one silver halide emulsion layer contains a compound represented by the following general formula (I) ##STR1## wherein Z represents an oxygen atom or a sulfur atom; R.sub.101 and R.sub.102, which may be the same or different, represent each an alkyl group and at least one of R.sub.101 and R.sub.102 is a butyl group, a pentyl group, a hexyl group, a heptyl group or an octyl group; V.sub.1, V.sub.2, V.sub.3, V.sub.4, V.sub.5, V.sub.6, V.sub.7 and V.sub.8, which may be the same or different, each represent a hydrogen atom, a halogen atom, an alkyl group, an acyl group, an acyloxy group, an alkoxycarbonyl group, a carbamoyl group, a sulfamoyl group, a carboxyl group, a cyano group, an alkoxy group, an alkylthio group, an alkylsulfonyl group, a sulfo group or an aryl group; of V.sub.1 to V.sub.8, two groups attached to neighboring carbon atoms do not combine together to form a condensed ring, and when each Hammett's .sigma.p value is referred to as .sigma.pi(i=1.about.8) and Y=.sigma.p1+.sigma.p2+.sigma.p3+.sigma.p4+.sigma.p5+.sigma.p6+.sigma.p7+.s igma.p8, Y.ltoreq.-0.08 where Z is an oxygen atom or Y.ltoreq.-0.15 where Z is a sulfur atom; X represents a counter ion; and n represents a value required for the neutralization of electric charge; and the ratio (V.sub.o /V.sub.g) of the total volume (V.sub.o) of oil droplets present in said silver halide emulsion layer to the total volume (V.sub.g) of hydrophilic colloid present therein is 0.8 or greater.
