Abstract (en)
A method for processing a silver halide color photographic material containing at least one pyrazoloazole magenta coupler represented by general formula (I), which comprises processing the light-sensitive material, after imagewise exposure, with a color developer containing an aromatic primary amine color developing agent and at least one member selected from among hydrazines and hydrazides represented by general formula (II): <CHEM> wherein R11 represents a hydrogen atom or a substituent, X represents a hydrogen atom or a group capable of being eliminated by a coupling reaction with an oxidation product of an aromatic primary amine developing agent, Za, Zb and Zc each represents a methine group, a substituted methine group, =N- or -NH-, provided that one of the Za-Zb bond and the Zb-Zc bond is a double bond and the other is a single bond and, when Zb-Zc is a carbon-to carbon double bond, it may be a part of an aromatic ring, and a dimer or higher polymer may be formed at R11 or X, or, when Za, Zb or Zc represents a substituted methine group, a dimer or higher polymer may be formed at the substituted methine group; <CHEM> wherein R<1>, R<2> and R<3> each independently represents a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group, R<4> represents a hydrogen atom, a hydroxy group, a hydrazino group, an alkyl group, an aryl group, a heterocyclic group, an alkoxy group, an aryloxy group, a carbamoyl group or an amino group, X<1> represents a divalent group, and n represents 0 or 1, provided that, when n is 0, R<4> represents an alkyl group, an aryl grbup or a heterocyclic group, and that R<3> and R<4> may together form a heterocyclic ring.
