Definitions

  • the present invention relates to color photography andparticularly to a method and means for inhibiting the fading of cyan dyes in color photographic materials in which color images have been formed by color develop ment with a primary amino developing agent.
  • a further object is to provide a composition which will function to prevent cyan dye fading in such color developed prints and transparencies.
  • the concentration of the water soluble salts employed ranges from 1 to 5 grams per liter when added to the wash water, or from 1, to SO-grams per liter when used in a. final rinse bath. 1
  • the following table shows the stabilizing effect on cyan dye images produced as subsequently noted, of treating color prints or transparencies with a final bath contain-J ing, i.e., cadmium bromide.
  • Said photographic multicolor materials include, color reversible film, color negative film, color reversible white printing material coated on an opaque base, and color positive printing'material coated on paper.
  • the multilayer color reversible film containing color formers may be prepared by the methods described in U.S.'Patents 2,179,228; 2,179,239; 2,186,849; and 2,220,187, and con sists of an integral tripack emulsion coated on the usual clear film .base.
  • Each of the emulsions is sensitized to one of the primary colors, namely, blue, green, and red.
  • the top layer is blue sensitive.
  • the filter layer yellow in color and blue absorbing, lies beneath the top layer. Below the said filter layer lies a green sensitive emulsion layer, and below this is a red sensitive emulsion layer.
  • Each of the three emulsion layers contains a dye forming compound fast to diffusion which, during the development of a silver image by an aromatic amino developing agent forms, with the oxidation product of said developing agent, a cyan quinoneimine from a phenol coupler in the red sensitive layer, a yellow azomethine from an open chain ketomethylene coupler in the blue sensitive layer and a magenta azomethine from a pyrazoline coupler in the green sensitive layer.
  • the developed dye image is complementary in color to the color for which the emulsion layer is sensitized. A combination of these three printing primaries results in production of all the various hues and shades in the finished film or print.
  • bleach solutions of the second type include those which contain a halide and an oxidizing agent such as an'alkali ferricyanide, a cupric salt, or an alkali dichromate.
  • the colored negative film is identical to the color reversible film with the exception that the former may contain an anti-abrasion layer or clear gelatin over the blue sensitive upper layer.
  • the color reversible white opaque material is made in the same manner as the color reversible film and the color negative film with the exception that an opaque white pigment is incorporated into the film base.
  • the positive color paper is also identical tothe color reversible film and the color negative film with the exception that a baryta coated paper base is used to hold theemulsion.
  • the above-described negative, positive, and reversible materials also differ as to the relative speed and contrast of the individual emulsion layers and of the multilayer color materials. Preparation of photographic multilayer materials containing specific color formers fast to difiusion has been ture pertaining to color photography and is therefore not herein described.
  • Example I The final treating bath is prepared as follows:
  • Example III Magnesium sulfate (71-1 0) gm.-- 50.0 Formalin ml. 15.0
  • reaction product of Example I Deionized water liters 1.0
  • Example IV Cadmium bromide gm. 2.0 Deionized water liters 1.0
  • the pH of this solution was adjusted to 6.5 by the use of a small amount of a sodium acetate-acetic acid butler solution.
