摘要:
A method of processing a silver halide color photographic material, which comprises processing a photographic material containing at least one pyrazoloazole type magenta coupler represented by the general formula (I) in a final bath containing a soluble iron salt in an amount of at least 1.times.10.sup.-4 mol/l, whereby marked improvements in stabilization of color images, especially cyan dye images and prevention of yellow stain are achieved: ##STR1## wherein R.sub.1 represents a hydrogen atom or a substituent, X represents a hydrogen atom or a group capable of being eliminated by the coupling reaction with an oxidation product of an aromatic primary amine developing agent, and Z.sub.a, Z.sub.b and Z.sub.c each represents methine group, a substituted methine group, .dbd.N-- or --NH--, provided that one of the Z.sub.a -Z.sub.b and Z.sub.b -Z.sub.c bonds is a double bond and the other is a single bond, in which when it represents a double bond the Z.sub.b -Z.sub.c bond includes one which constitutes a part of an aromatic ring, and further, the substituent R.sub.1 or X, or the substituted methine represented by Z.sub.a, Z.sub.b or Z.sub.c may form a polymer including a dimer.
