Abstract
The present invention, relates to a method for the bleaching-fixation processing of silver halide color photographic materials. The present invention provides for sufficient desilvering in a short period of time without deterioration of the photographic characteristic of the materials as processed while minimizing the amount of replenisher which is used. Accordingly, the present invention is a method for the processing of silver halide color photographic materials wherein, after the color-development, the material is processed by bleaching-fixation with at least two continuous bleaching-fixation baths to which a replenisher is fed in a countercurrent system, wherein the total bleaching-fixation processing time in the bleaching-fixation step is to be 0.37 minutes or more per g/m.sup.2 of the silver amount coated on the material and wherein the processing time in the first bleaching-fixation bath is to be 45% or less of the total bleaching-fixation processing time.
