摘要： A silver halide photographic material containing at least one of couplers represented by the general formula (I) and at least one of the compounds represented by the general formula [XII] is disclosed. Formula [I]
wherein Z is a group of nonmetal atoms necessary to complete a nitrogen-containing heterocyclic ring where the ring formed by Z may be substituted; X is a hydrogen atom or a substituent capable of being released upon reaction with the oxidation product of a color developing agent and R is a hydrogen atom or substituent;
wherein R 21 is a hydrogen atom or a group selected from the group consisting of an alkyl group, an alkenyl group, a cycloalkyl group and aryl group, R 22 and R 23 are independently selected from the group consisting of an alkyl group, an alkenyl group, a cycloalkyl group and an aryl group. The photographic material provides a dye-image highly stable against heat and light, and a formation of stain at a non-image area is prevented.
