ABSTRACT:
Processing a silver halide color photographic material comprising color developing, desilvering and water washing and/or stabilizing. In this process, a photographic material which has at least one emulsion layer containing a high silver chloride content, and at least one emulsion layer containing a monodisperse emulsion, is continuously processed with a color developing solution containing a water-soluble high polymer compound. The coated amount of silver in the photographic material is preferably 0.75 g/m.sup.2 or less. The color developing solution preferably has a chloride ion content of 0.035 mol/l or more. The water soluble high polymer compound can be a polyester, polyamide, polyurethane, polyether, polycarbonate or a natural high polymer compound, or their derivatives. It is obtained by polymerizing or copolymerizing a monomer containing a copolymerizable ethylene type unsaturated group. The high polymer compound is preferably added in the amount of 0.001-10 g per liter of the color developing solution. By using this process, fluctuations in photographic properties is remarkably reduced, uniformity in developed density is remarkably improved, and the prevention of deposits on the processing tank wall surface is improved.
