Zusammenfassung:BLEACH-ACCELERATING COMPOSITIONS CONTAINING A DYE-STABILIZING AGENT AND USE THEREOF IN PHOTOGRAPHIC COLOR PROCESSING Improved bleach-accelerating compositions that are especially useful in the reversal color processing of photographic elements are comprised of bleach-accelerating agent and a dye-stabilizing agent. Formaldehyde precursors function as particularly effective dye-stabilizing agents in such compositions. The bleach-accelerating composition is utilized subsequent to the color developing step and prior to the bleaching step and serves to enhance the effectiveness of the bleaching step and to provide improved dye stability.
