Abstract

Abstract A silver halide photographic material is disclosed which has formed on a support in sequence a silver halide emulsion layer incorporating a yellow coupler of the formula (I), a silver halide emulsion layer incorporating a magenta coupler of the formula (II), and a silver halide emulsion layer incorporating a cyan coupler of the formula (III): <IMAGE> (I) wherein R1 is a hydrogen atom, a halogen atom or an alkoxy group; R2 is -NHCOR3, -NHSO2R3, -COOR3 or <IMAGE> provided that R3 and R4 are each an alkyl group; and Z1 is a non-metallic atomic group necessary to form a 5- or 6-membered hetero ring together with a nitrogen atom); <IMAGE> (II) [wherein R5 is a hydrogen atom, a halogen atom or an alkoxy group having 1 to 4 carbon atoms; R6 is <IMAGE> (provided that R7 and R8 are each a hydrogen atom or an acyl group, and when R7 and R8 are each an acyl group, they may be combined to form a 5-membered hetero ring together with a nitrogen atom), an alkyl- or arylsulfonamido group, an alkyl- or arylsulfamoyl group or an alkyl- or arylcarboxylic acid ester group; Y1, Y2, and Y3 are each a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a carboxy group, an alkoxycarbonyl group, a nitro group, an aryloxy group, a cyano group or an acylamino group; and Z2 is an atom or a group that leaves when it enters into a coupling reaction with the oxidation product of a color developing agent]; <IMAGE> (III) (wherein R9 is a straight- or branched-chain alkyl group having 2 to 4 carbon atoms; and R10 is a ballast group).
