ABSTRACT:
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. This solution is provided in highly concentrated form and diluted up to 9:1 prior to or during use. The concentrate contains a formaldehyde precursor at 200 to 450 g/l, a sulfite at from 40 to 100 g/l, a bleach accelerating agent at 1.5 to 13.5, and a metal ion chelating agent at 5 to 45 g/l.
