Abstract
Abstract A silver halide color photographic material composed of a support having thereon at least one light-sensitive silver halide emulsion layer containing a color coupler, at least one layer of the material containing a compound represented by formula: wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 , which may be the same or different, each represents hydrogen, a halogen atom, a sulfo group, a carboxyl group, a cyano group, an alkyl group, an aryl group, an acylamino group, a sulfonamido group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, an acyl group, an acyioxy group, a sulfonyl group, a carbamoyl group, an alkoxycarbonyl group or a sulfamoyl group; provided that R' and R 2 , or R 4 and R 5 may each be linked to form a carbon ring or a heterocyclic ring; and Z represents a single bond or a divalent linking group. The silver halide color photographic material provides an image having an improved white background and gradation, and low minimum image density.
