摘要： Bleach compositions and methods that are improvements over those provided by Fyson, U.S. Pat. No. 4,294,914, are disclosed. A highly preferred bleach composition of this invention (a) has the ferric complex of methyliminodiacetic acid as a bleaching agent, and additionally comprises (b) at least 0.9 mole of acetic acid per liter, (c) from about 15 to about 35 grams per liter of potassium bromide; and (d) has a pH of from about 2.5 to about 4.0.This invention includes the discovery of a synergistic bleaching coaction of a bleach (i) comprising an alkyliminodiacetic acid such as methyliminodiacetic acid, and (ii) which has a pH of from about 3.5 to about 4.5 , and (iii) in which the amount of ferric iron is from about 2 to about 16 grams per liter. This coaction between iron levels and pH was previously unknown and was unexpected.Bleach formulations of this invention can be used in the processing of color photographic materials, such as film.

摘要： An environmentally advantageous photographic bleaching solution for use in the color processing of photographic elements comprises (1) as a bleaching agent, a potassium salt of a ferric complex of an aminopolycarobxylic acid, (2) as an agent which functions to convert silver to silver halide, a potassium halide, and (3) as an agent which functions to inhibit bleach induced dye formation, a water-soluble aliphatic carboxylic acid. The bleaching solution is especially useful in the processing of photographic elements containing a low pKa, high-activity, yellow-dye-forming coupler in that it serves to effectively avoid the undesirable increase in blue D.sub.min that can occur in such elements as a result of bleach induced dye formation.
摘要翻译：用于照相元件的彩色处理的环境有利的照相漂白溶液包括（1）作为漂白剂，氨基多焦硬脂酸的铁配合物的钾盐，（2）作为将银转化成卤化银的作用剂，卤化钾，和（3）作为抑制漂白剂诱导的染料形成的作用剂，水溶性脂族羧酸。漂白溶液特别适用于加工含有低pKa，高活性，形成黄色染料的成色剂的感光元件，因为它有效地避免了由于这些元素可能发生的蓝色Dmin的不期望的增加，漂白剂诱导染料形成。

摘要： Bleaching and bleach-fixing solutions, especially useful in the processing of a photographic color material, contain a bleaching agent comprising a ferric complex of propylenediaminetetraacetic acid and a hydroxy-substituted chelating agent present in an amount sufficient to reduce the formation of ferric propylenediaminetetraacetic acid precipitates. The solutions do not generate unacceptable stain or adversely affect leuco cyan dye recovery or process cleanliness.
