Abstract
Abstract A method for processing a light-sensitive silver halide color photographic material by developing a light-sensitive silver halide color photographic material after imagewise exposure with a color developing solution containing a p-phenylenediamine type color developing agent containing at least one water-soluble group on its amino group and then subjecting the developed material to direct processing with a bleach-fixing solution kept in a state of being oxidized, which comprises using a diethylenetriaminepentaacetic acid iron (III) complex as the bleaching agent for said bleach-fixing processing.
