Abstract
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.⊖ 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 1 , R 2 , R 6 and R 8 , which may be the same or different, each represents a hydrogen atom or a lower alkyl group; R 3 , R 4 and R 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 3 , R 4 and R 5 may combine with each other to form a ring; said R 3 , R 4 or R 5 and said R 1 or R 2 may combine with each other to form a ring; and R 7 represents --NR 9 R 10 --OR 11 , or --SR 11 (wherein, R 9 and R 10 , which may be the same or different, each represents a hydrogen atom or a lower alkyl group; R 11 represents an atomic group necessary for forming a ring by combining with R 6 ; and said R 9 or R 10 and said R 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.
