Definitions
- a second method involving no substantial change in the manufacture of the sensitive material described in the previous patents and application referred to, is to separate the treatment of the developed, fixed and washed film or plate for subsequent coloring by methods of controlled diffusion of chemical solutions employed as disclosed in our prior patents.
- the coatings may be simultaneously bleached in potassium ferricyanide and the upper one (or two in the case .of triple-coating) alone redeveloped by controlled diffusion of a concentrated developer.
- the undeveloped lower layer still containing an image-record in silver ferrocyanide, may be developed by immersionin a color-forming developer as described above which will not affect the redeveloped silver of the upper layer or layers.
- the plate, or film may be fixed in sodium thiosulfate, washed, and then dried, and the remaining layer or layers bleached tosilver ferrocyanide, for redevelopment in another color-forming developer, and so on to the third coating in 5 the case ofthree-color photography.
- the remaining metallic silver formed in the color developers is removed by solution in sodium thiosulfate and potassium ferrocyanide, or some other solvent of silver.
- the colored negative is printed on a similarly coated positive which in turn is color-developed substantially as described for the negative.
- the surface record may be dissolved and removed after drying and the remaining lower layers treated for the two colors only. This method of treatment of the exposed plate may also be applied to triple coatings.
- Paraphenylenediamines and paramidophenols are typical developers used in conjunction with the color-formers.
