  • Method of processing color negative elements
    Patent number: 6482579
    Abstract: Color negative photographic elements can be effectively processed to provide negative 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.
    Type: Grant
