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.

Photographic stabilizing processing solution and method of use

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. The color films can be more rapidly processed, for example, within 60 seconds for the stabilizing step.

Method of rapid processing using a stabilizing solution

Color photographic materials are processed using a final rinse solution containing a water-soluble or water-dispersible glycol, 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 solution provides processed materials, with or without a magnetic backing layer, that are free of scum or other residues, non-tacky, and resistant to abrasion and fingerprinting. The final rinse solution can be provided in concentrated form, particularly because the glycol is included.

Photographic final rinse processing solution and method of use

Photographic films having a magnetic recording layer are processed using a final processing solution containing a mixture of surfactants. The final processing solution can be a final rinse solution or an image stabilizing solution further containing an image stabilizer. The specific final processing solution composition provides processed films that are free of scum, non-tacky, and resistant to abrasion and fingerprinting on the back side.
