ABSTRACT:
A process for processing a silver halide color photographic material is described comprising subjecting a silver halide color photographic material comprising a support having provided thereon at least one photographic emulsion layer containing at least one kind of pyrazoloazole series magenta coupler represented by general formula (I) to photographic processing using a bath containing at least 1.times.10.sup.-4 mol/liter of a soluble iron salt as the final bath: ##STR1## wherein Za and Zb each represents .dbd.CH--, (wherein R.sub.2 represents a hydrogen atom or a substituent) or =N-; R.sub.1 represents a hydrogen atom or a substituent; X represents a hydrogen atom or a group releasably upon coupling with the oxidation product of an aromatic primary amine developing agent; when Za=Zb is a carbon-carbon double bond, the double bond may be a part of an aromatic ring; the magenta coupler may form a dimer or polymer at R.sub.1, R.sub.2 or X; when at least one of said Za and Zb is ##STR2## at least one of the R.sub.1 and R.sub.2 represents a methylene group directly bonded to the skeleton of general formula (I), at least one of the hydrogen atoms of which is substituted; when both Za and Zb are .dbd.N--, R.sub.1 is a methylene group directly bonded to the skeleton, at least one of the hydrogen atoms of which is substituted; and the R.sub.1 or R.sub.2 has at least one --NHSO.sub.2 -- as a substituent.
