A conditioning or bleach accelerating solution can be used to process color photographic films, especially color reversal films, to minimize magenta dye fade while reducing the needed amount of formaldehyde stabilizer. These advantageous effects are achieved by including a secondary amine in the solution along with a formaldehyde precursor and a bleach accelerator.
