ABSTRACT:
A method for processing a silver halide color photographic material by subjecting a light-exposed silver halide color photographic material to a color development and then subjecting it to bleach processing and fix processing or to blix processing, which comprises performing said bleach processing or blix processing using a bleach bath or a blix bath containing a ferric ion complex salt as a bleaching agent, said bleach bath or blix bath, or a prebath for said bath containing at least one of compounds represented by the following general formula (I) or (II); ##STR1## wherein, X represents a hydrogen atom, ##STR2## Y.sup..crclbar. represents an anion; Q represents an atomic group necessary for forming a quaternary nitrogen-containing unsaturated heterocyclic ring; n represents an integer of 1 to 5; R.sup.1, R.sup.2, R.sup.6 and R.sup.8, which may be the same or different, each represents a hydrogen atom or a lower alkyl group; R.sup.3, R.sup.4 and R.sup.5, which may be the same or different, each represents a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group; any two of said R.sup.3, R.sup.4 and R.sup.5 may combine with each other to form a ring; said R.sup.3, R.sup.4 or R.sup.5 and said R.sup.1 or R.sup.2 may combine with each other to form a ring; and R.sup.7 represents --NR.sup.9 R.sup.10 --OR.sup.11, or --SR.sup.11 (wherein, R.sup.9 and R.sup.10, which may be the same or different, each represents a hydrogen atom or a lower alkyl group; R.sup.11 represents an atomic group necessary for forming a ring by combining with R.sup.6 ; and said R.sup.9 or R.sup.10 and said R.sup.6 may combine with each other to form a ring).
The method of the present invention does not produce poisonous materials which are harmful to the environment and provides an excellent high speed bleaching process without harming other photographic properties.
