ABSTRACT:
Concentrated and working strength photographic fixing compositions include a photographic fixing agent, a triazinylstilbene compound, and a water-soluble stabilizing compound that has a molecular weight of less than 200, from 2 to 10 carbon atoms, and at least two amino or hydroxy functional groups. The triazinylstilbene is provided in a concentrated fixer additive composition in a mixture with the stabilizing compound. The fixing compositions also include predominantly ammonium ions, and can be used to provide images in color photographic materials, and particularly in color reversal films, with reduced residual sensitizing dye stain.
