【発明の名称】写真漂白液及び写真カラー処理におけるその使用
Document Type and Number:
Japanese Patent JPH05503791
Kind Code:
A
Abstract:
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 aminopolycarboxylic 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 Dmin that can occur in such elements as a result of bleach induced dye formation.
