    • 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.
    • 加工卤化银彩色照相材料,包括彩色显影,脱色和水洗和/或稳定化。 在该方法中,使用含有高氯化银含量的至少一种乳剂层和至少一种含有单分散乳液的乳剂层,用含有水溶性高分子化合物的显色液连续地进行处理。 照相材料中的银的涂布量优选为0.75g / m 2以下。 显色溶液的氯离子含量优选为0.035mol / l以上。 水溶性高分子化合物可以是聚酯,聚酰胺,聚氨酯,聚醚,聚碳酸酯或天然高分子化合物或它们的衍生物。 通过聚合或共聚含有可共聚的乙烯型不饱和基团的单体获得。 高分子化合物的添加量优选为每升显色液0.001-10g。 通过使用该方法,显着降低了照相特性的波动,显着提高了显影浓度的均匀性,提高了防止处理罐壁面上的沉积。
