Abstract
379,934. Colour photography. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Dec. 7, 1931, No. 33921. Convention date, Dec. 6, 1930. [Class 98 (ii).] Relates to photographic material comprising superposed light-sensitive layers dyed with dyestuffs corresponding to the final coloration of the picture, and consists in adding to one or more of the layers a filter dyestuff which absorbs at least part of the spectral region of permeability or sensitiveness of such layer in order to adapt the gradations of the layers to one another, the filter dyestuff being decolorized in the photographic treatment baths. Methyl Blue, Tartrazine and Acid Fuchsine are specified for red, blue and green layers respectively. In examples (1) a support is coated on one side with a light-sensitive emulsion dyed with Diamine Green and on the other with an emulsion dyed with a mixture of Salicin Orange and Benzo Light Red, together with Methyl Blue ; (2) a three-colour film comprises a first emulsion layer coloured blue-green with Brilliant Benzo Fast Green, a second layer coloured purple by Sirius Red-violet or Sirius Ruby, and a third layer coloured yellow by Benzo Light Yellow, the sensitiveness to red, green and blue light of the respective layers being modified respectively by Methyl Blue, Acid Fuchsine and Tartrazine. The Specification as open to inspection under Sect. 91 (3) (a) refers also to stereophotography. This subject-matter does not appear in the Specification as accepted.
