Abstract (en)

A processing method for silver halide color photographic material and a bleaching solution used in the processing are disclosed. Sufficient desilvering in a short time and prevention of bleaching fogging can be obtained by the process. The process is applicable for silver-rich high-sensitivity color light-sensitive material. The bleaching solution comprises a of a ferric complex salts of compounds represented by the following Formula A or B in an amount of at least 0.01 mol per liter of the bleaching solution and a buffer agent capable of adjusting pH value to 3 to 7; and pH value of the bleaching solution is held within the range of from 3 to 7; <CHEM> wherein A1 through A4 are each -CH2OH, -COOM, or -PO3M1M2; M, M1 and M3 are each a hydrogen atom, a sodium atom. a potassium atom or an ammonium group; X is a substituted or unsubstituted alkylene group having three to six carbon atoms; B1 and B2 are a substituted or unsubstituted alkylene group having two to five carbon atoms; n is an integer of 1 to 8.
