    摘要： Color reversal or color negative photographic elements can be effectively processed to provide positive color images using bleaching or bleach-fixing compositions in which the primary bleaching agent is a ferric complex of 1,3-propylenediaminetetraacetic acid or a salt thereof. Any potential precipitation of the bleaching agent is inhibited by the presence of at least 0.005 mol/l of an organic polyphosphonic acid, an aminopolysuccinic acid, or a polycarboxylic acid containing at least one hydroxy group as a compound. This compound can be added directly to the bleaching or bleach-fixing composition or introduced from carryover from a previous photoprocessing step, such as a prebleaching step using color reversal processing.

    摘要翻译： 彩色反转或彩色负照相元件可被处理以有效地提供使用的漂白或漂白 - 定影组合物，其中主要漂白剂是1,3-丙二胺四乙酸或其盐的三价铁配合积极的彩色图像。 漂白剂的任何潜在的沉淀是通过至少0.005摩尔/升的有机聚膦酸的存在抑制到aminopolysuccinic酸，或聚羧酸含有至少一个羟基基团作为化合物。 该化合物可以直接加入到漂白或漂白 - 定影组合物，或从先前的照片处理步骤中，检测与使用彩色反转处理的预漂白步骤结转介绍。
