    • A single-part, single-phase liquid color developer concentrate for color photographic development having at least one color developing agent of p-phenylenediamine or a derivative or salt thereof, an aqueous solution containing one or more organic solvents in a weight ratio of water to the organic solvent greater than or equal to about 60:40, a molar ratio of [Na ]/[K ] of at least about 1:2, preferably at least about 2:1, and/or a molar ratio of the organic solvent of Formula (I) to a free base of the p-phenylendiamine or P-phenylendiamide derivative is from about 3:1 to about 30:1 is described. The color developer concentrate is simple to manufacture, stable, compact, easy to use, has good water solubility upon dilution, minimizes mixing errors, and can be used with a very low replenishment rate. A method for processing image-wise exposed photographic color silver halide emulsions using the single-part, single-phase liquid color developer concentrate is also provided.
    • 用于彩色照相显影的单组分单相液体显色剂浓缩物,其具有至少一种对苯二胺或其衍生物或盐的显色剂,含有一种或多种有机溶剂的水溶液,其重量比为水与 有机溶剂大于或等于约60:40,[Na +] / [K +]的摩尔比为至少约1:2,优选至少约2:1,和/或 描述了式(I)的有机溶剂与对苯二胺或对苯二酰胺衍生物的游离碱的摩尔比为约3:1至约30:1。 彩色显影剂浓缩物易于制造,稳定,紧凑,易于使用,在稀释时具有良好的水溶性,最小化混合误差,并且可以以非常低的补充速率使用。 还提供了使用单份单相液体显色剂浓缩物处理图像曝光的照相彩色卤化银乳剂的方法。
