ABSTRACT:
A method for processing a light-sensitive silver halide color photographic material including color developing processing, and fixing. The bleaching is with a bleaching solution containing at least one of ferric complexes of the compounds represented by the formula (A) or (b) shown below and has a pH of 2.0 to 5.5. The fixing is with a processing solution having fixing ability and which contains at least one mole/liter of a thiosulfate. Said processing solution having fixing ability contains a compound selected from the group (FB). ##STR1## wherein A.sub.1 to A.sub.4 may be either the same or different, and each represent --CH.sub.2 OH, --COOM or --PO.sub.3 M.sub.1 M.sub.2 ; M, M.sub.1 and M.sub.2 each represent hydrogen atom, sodium atom, potassium atom or ammonium group; X represents a substituted or unsubstituted alkylene group having 3 to 6 carbon atoms, ##STR2## wherein A.sub.1 to A.sub.4 may be either the same or different and each represent --CH.sub.2 OH, --COOM or --PO.sub.3 M.sub.1 M.sub.2 ; M, M.sub.1 and M.sub.2 each represent hydrogen atom, sodium atom, potassium atom or ammonium group; n represents an integer of 1 to 8; B.sub.1 and B.sub.2 each represent a substituted or unsubstituted alkylene group having 2 to 5 carbon atoms, which may be either the same or different, and (FB) is thiourea, ammonium iodide, potassium iodide, ammonium thiocyanate, potassium thiocyanate, sodium thiocyanate or thiocyanocatechol.
