发明名称 Cyan dye recovery using ferric aminopolycarboxylic acid bleaching composition
摘要 <p>Cyan dye density can be maximized in color developed silver halide photographic color materials and bleaching accelerated by contacting the materials with a bleaching or bleach-fixing composition comprising a ferric complex of an aminopolycarboxylic acid as a bleaching agent, and an aromatic pyridinyl mono- or dicarboxylic acid in uncomplexed form. The molar ratio of the aromatic carboxylic acid to the ferric ion in the bleaching agent is from 0.02:1 to 0.8:1. &lt;IMAGE&gt;</p>
