  • the black and white negative material After development, the black and white negative material, without being fixed, is exposed to general illumination, followed by a second development with a color forming developer. Duringthe first and second development, the silver-halides in all the layers are reduced to metallic silver. After the s c nd develo n he m i is cleared in running'water, hardened in an aqueous solution consisting of either alum or potassium c om a um andt n as in unning water- Aiter the latter treatment, the silver present all the layers formed during the first and second d elo men is co v ted i a sa by and 9f the known silver-salt formers, as bleaching baths, and the silver-salt $11311 iormedis then removed by dissolvingitin a silver-.- salt solvent such as, for example, hypo. The material is then washed for .a long period of timeand then dried.

  • the water-soluble products while utilizing the azines of Formulae 2 and 3 are prepared according to the methods described in United States Patents, 2,211,? 10 and 2,211,709, respectively.
  • the concentration of the addition products required may vary from as little as 0.5%, an amount which in general has been found to eliminate stain for the most part, to as much as 5%, an amount which is an assurance that stain formation will not ensue. Amounts higher than 5% give little improvement. Concentrations ranging from between 2 and 4% are most desirable from a commercial standpoint.
  • the photographic multi-layer materials which may be processed with the anti-stain bath of the present invention, are color reversible film, color negative film, color reversible white printing material coated on an opaque base, and color positive printing material coated on paper, irrespective of whether the dyestuff images are produced with color formers present in the emulsion, or by a selective second exposure followed by development with developing solutions containing color formers and color developing agents.
  • the color reversible film consists of an integral tripack emulsion coated on the usual clear cellulose acetate or nitrate film base. Each of the emulsion are sensitized to one of the primary colors of light, namely, blue, green, and red.
  • the top layer is blue sensitive.
  • a filter layer, yellow in color and blue absorbing, lies under the top layer. Below this filter layer, lies a green sensitive emulsion layer, and below this is a red sensitive emulsion layer.
  • Each of the three silver-halide emulsion layers contain dye-forming compounds which unite during the development of a silver image in an aromatic amine developing agent to form a dye with the oxidation product of the developing agent, or may be free from color formers in which case the film is processed with the color formers in the color developers by the selective second exposure and color development method as described in United States Patents 1,897,866, 1,900,870, 1,928,709 and 1,980,941.
  • a yellow dye is formed in the blue sensitive emulsion; a magenta dye is formed in the green sensitive emulsion; and a cyan dye is formed in the red sensitive emulsion. Combinations of these 4 three printing primaries will produce all of the other colors in the finished film or print.
  • the color negative film is made up in the same: manner as the color reversible film with the ex-- ception that it may contain a layer of clear" gelatin between the red sensitive layer and the green sensitive layer.
  • the color reversible white opaque material is prepared in the same manner as color reversible film and the color negative film with the exception that the base consists of an opaque white film.
  • the color paper is also constructed in the same manner as the color reversible film and the color negative film, with the exception that the emulsion is coated on a baryta coated paper base. Suitable methods for the preparation of photographic multi--layer materials have been described in the literature relating to color photography and are, therefore, not described here.
  • Example I A 4" x 5" full color transparency sheet of color.” film was printed by contact on two 4" x 5" sheets of color reversible white opaque film.
  • the film was washed for two minutes in running water 68 F. and re-exposed to white light.
  • the re-exposed film was color developed for fifteen minutes at 68 F. in a developer of the following composition:
  • Example II Example III Example I was repeated with the exception that the colored material employed was a color transparency sheet and the final rinse bath consisted of 97 parts by weight of water and 3 parts by weight of a water-soluble addition product of formaldehyde and melamine, trimethylolmelamine, prepared according to Example VI of United States Patent 2,197,357. After fixing and washing, the color print washed in water showed objectionable stains, while the color print treated with the aqueous solution containing the addition product was clear and unstained.
  • the colored material employed was a color transparency sheet and the final rinse bath consisted of 97 parts by weight of water and 3 parts by weight of a water-soluble addition product of formaldehyde and melamine, trimethylolmelamine, prepared according to Example VI of United States Patent 2,197,357.
  • Example IV Example IV was repeated with the exception that the final rinse consisted of 98 parts by weight of water and 2 parts by weight of trimethylolmelamine available commercially under the brand name of "I a-rial: MR1! and having the fol-lowing formula:
  • the treated and untreated prints of Examples 11 to IV inclusive were stored for several months.
  • the untreated prints showed marked staining during storage and the color balance after storage was completely ruined by yellow stains, whereas no stains were evident on the treated prints and the color balance was unafiected.
  • water-soluble addition products of formaldehyde and an azine in aqueous solutions as a final rinse bath, they may be incorporated into gelatin solutions in a concentration ranging from 25% and such gelatin solutions utilized as a surface coating for the processed multi-layer photographic material.
  • At least one Y is an amino group having at least one reactive hydrogen atom, the remaining Ys being a radical selected from the group consisting of hydrogen, hydroxyl, halogen, alkyl, alkylene, aryl and aralkyl
  • Z represents a member selected from the group consisting of hydrogen amino, hydroxy, alkyl, alkoxy, phenyl, phenylene, mercapto, alkylthio and hydrazino, at least two Zs being a member selected from the class consisting of amino and hydrazino group
  • X represents a member selected from the groupconsisting of hydrogen and a primary amino group
  • R represents a member of the group consisting of halogen, hydroxy, hydrazino, alkoxy, phenyl, and alkylthio groups.
