ABSTRACT:
A method for processing a silver halide color photographic material is disclosed, wherein a washing bath is replenished with water in an amount of from 2 to 50 times the volume of the preceding bath which is carried over with the photographic material into the washing bath per unit area of the photographic material to be processed, and washing in the washing bath is carried out in the presence of at least one compound represented by formula (I): ##STR1## wherein A represents a n-valent aliphatic, aromatic or heterocyclic linking group, wherein when n is 1, A represents a monovalent aliphatic, aromatic, or heterocyclic group, or a hydrogen atom; X represents --O--, --S--, or ##STR2## R.sup.1 and R.sup.2 each represents substituted or unsubstituted lower alkyl group; R.sup.3 represents a lower alkylene group; R.sup.4 represents a lower alkyl group; or R.sup.1 and R.sup.2, R.sup.1 and A, R.sup.1 and R.sup.3, R.sup.2 and A, or R.sup.2 and R.sup.3 may be connected to each other to form a ring; Y represents an anion; l represents 0 or 1; m represents 0 or 1; n represents 1, 2, or 3; p represents 0 or 1; and q represents 0, 1, 2, or 3, and is a value which renders the molecule electrically neutral. The processing method can achieve a great saving of water for washing while protecting the processed color photographic material from mold, the formation of stains, and undergoing accelerated discoloration.
