## Abstract

A novel method for processing a silver halide color photographic material which comprises color developing an imagewise exposed silver halide color photographic material and then processing the material with a having a bleaching ability containing at least one bleaching agent a ferric complex of a compound represented by at least one of formula (I) and formula (II): ##STR1## wherein W.sup.1 represents an alkylene group containing 3 or less carbon atoms in total; L.sup.1, L.sup.2, L.sup.3 and L.sup.4 each represents an alkylene or arylene group; and M.sub.1 to M.sub.6 each represents a hydrogen atom or a cation; ##STR2## wherein W.sup.2 represents an alkylene group having 2 to 8 carbon atoms, an arylene group having 6 to 10 carbon atoms, cyclohexane group, ##STR3## (in which W.sup.21 and W.sup.22 each represents an alkylene group, and m represents an integer of 1 to 3, and A represents a hydrogen atom, hydrocarbon group, --L.sub.A --COOM, --L.sub.A --PO.sub.3 M.sub.2, --L.sub.A --OH or --L.sub.A --SO.sub.3 M (L.sub.A represents an alkylene group having 1 to 8 carbon atoms or an arylene group having 6 to 10 carbon atoms, and M represents a hydrogen atom or a cation such as an alkali metal or ammonium)), or a combination of theseof; L.sup.5, L.sup.6, L.sup.7 and L.sup.8 each represents an alkylene group; and M.sub.7, M.sub.8, M.sub.9, M.sub.10 and M.sub.11 each represents a hydrogen atom or a cation.

## Claims

### Claim 1

A method for processing a silver halide color photographic material comprising color developing an imagewise exposed silver halide color photographic material and then processing the material with a processing solution having a bleaching ability containing at least one bleaching agent; wherein said bleaching agent is a ferric complex of a compound represented by formula (II): ##STR27## wherein W.sup.2 represents an alkylene group having 2 to 8 carbon atoms, an arylene group having 6 to 10 carbon atoms, a cyclohexane group, ##STR28## in which W.sup.21 and W.sup.22 each represents an alkylene group, and m represents an integer of 1 to 3, and A represents a hydrogen atom, a hydrocarbon group, --L.sub.A --COOM, --L.sub.A --PO.sub.3 M.sub.2, --L.sub.A --OH, or --L.sub.A --SO.sub.3 M, where L.sub.A represents an alkylene group having 1 to 8 carbon atoms or an arylene group having 6 to 10 carbon atoms, and M represents a hydrogen atom or a cation, or a combination thereof; L.sup.5, L.sup.6, L.sup.7, and L.sup.8 each represents an alkylene group; and M.sub.7, M.sub.8, M.sub.9, M.sub.10 and M.sub.11 each represents a hydrogen atom or a cation;
