Abstract
Color photographic films are processed using a final dye image stabilizing solution containing certain aromatic or heterocyclic aldehydes, acetals or hemiacetals, and a mixture of specific surfactants. One surfactant is a nonionic polyethoxylated, nonfluorinated compound, or an anionic non-fluorinated sulfate or sulfonate, and the second surfactant is a nonionic or anionic fluorinated compound. This processing solution provides processed films, with or without a magnetic backing layer, that are free of scum or other residues, non-tacky, and resistant to abrasion and fingerprinting. The stabilizing solution can be provided in concentrated form, particularly when a glycol is included.
