Abstract
Abstract A silver halide color photographic material is disclosed which contains a magenta color image-forming coupler represented by the following formula (I) and a compound represented by the following formula (II): ##STR1## wherein Z represents the group of nonmetallic atoms necessary for forming a nitrogen-containing heterocyclic ring, provided that the ring to be formed by said Z may have a substitutent; X represents a hydrogen atom or a substituent capable of leaving upon reaction with the oxidized product of a color developing agent; and R represents a hydrogen atom or a substituent. ##STR2## wherein R 1 is an aliphatic group, a cycloalkyl group or an aryl group; and Y represents the group of nonmetallic atoms necessary for forming a 5- to 7-membered heterocyclic ring taken together with the nitrogen atom, provided that at least two hetero atoms among the heterocyclic ring-forming nonmetallic atoms including the nitrogen atom are not adjacent to each other.
