    Abstract: A method for the formation of a color photographic image comprising exposure and development of a photographic element, said photographic element comprising at least one silver halide emulsion layer, a compound capable of releasing a diffusible azo dye compound during development, and at least one mordant layer arranged on a support. The color image formation is effected by the reaction of multivalent metallic ions with an azo dye compound having the formula: ##STR1## wherein G.sup.1 is an alkoxy or a thioalkoxy metallic chelating group; G.sup.2 is a metallic chelating group in which an oxygen atom is involved in the chelate formation; and Z.sup.1 and Z.sup.2 each is a group of atoms necessary to form an aromatic carbocyclic ring or a heterocyclic ring. The azo dye compound and the metallic ions form a metal complex by coordination of the azo group and the G.sup.1 and G.sup.2 groups of the azo dye compound with the multivalent metallic ions.

  • Patent number: 4370402
    Abstract: There is disclosed an aqueous composition for removing or reducing the intensity of dyes in dye transfers and the intensity of dyes used by photo retouchers on transparencies and color prints. The composition comprises, per 100 parts by weight of water, from about 1 to about 10 parts by weight of a thiourea and from about 5 to about 20 parts by weight of an ammonium nitrate compound. Application of this composition to dye transfers and/or to dyes used by photo retouchers on transparencies and color prints proportionally removes magenta, cyan and yellow dyes therefrom.
