摘要:
The present invention provides an economical method for the processing of silver halide color photographic materials comprising fixing or bleach-fixing of the material followed by the washing thereof with a small amount of a washing replenisher. The present method is characterized in that the silver halide color photographic material to be processed contains at least one cyan dye-forming coupler of the following formula (I) or (II) and that the amount of the washing replenisher in the washing step falls within the range of 30 to 50 times of the amount of the processing solution carried over from a previous bath based on the unit area of the photographic material being processed, ##STR1## wherein, R.sub.1 represents --CONR.sub.5 R.sub.6, --NHCOR.sub.5, --NHCOOR.sub.7, --NHSO.sub.2 R.sub.7, --NHCONR.sub.5 R.sub.6 or --NHSO.sub.2 NR.sub.5 R.sub.6 ;R.sub.2 represents a substituent on the naphthol ring;m is an integer of 0 to 3;R.sub.3 represents a mono-valent organic group;R.sub.4 represents a substituted or unsubstituted aryl group;X represents a hydrogen atom or a group capable of being released by the coupling reaction with an oxidized aromatic primary amine developing agent;R.sub.5 and R.sub.6 each represents a hydrogen atom, an aliphatic group, an aromatic group or a heterocyclic group;R.sub.7 represents an aliphatic group, an aromatic group or a heterocyclic group;when m is a plural number in the formula, R.sub.2 's may be the same or different or may be bonded to each other to form a ring; andR.sub.2 and R.sub.3, or R.sub.3 and X may be bonded to each other to form a ring.According to the present method, the thermal discoloration of cyan dyes may be prevented and the stability with lapse of time thereof may be improved, and the amount of the washing solution to be used in the washing step may be noticeably reduced.
