Abstract
205,807. Schapovaloff, S. Oct. 20, 1922, [Convention date]. Colour photography; plates and films with multiple sensitive layers; films, stripping.- Plates having superposed emulsion layers, each carried by a separate support, for obtaining colour component negatives by direct exposure through a single lens, are produced by directly coating in succession the layers and their supports, and after exposure the layers, still adhering to their supports, are stripped apart for development, &c. In one instance a glass plate coated with a panchromatic emulsion layer is coated with a celluloid layer, and then with a layer of agglutinant, which may be dyed red or orange to serve as a screen for the panchromatic emulsion. An emulsion layer which is green-sensitive is then applied, followed by a layer of celluloid and a layer of agglutinant which may be dyed yellow or yellow-green to serve as a screen for the green sensitive layer. An emulsion layer sensitive to blue violet is then applied. The celluloid layers easily strip from the gelatin emulsion coatings on which they are coated. The Specification as open to inspection under Sect. 91 (3) (a) also states that in order to facilitate detachment, one corner of each film formed mav be left loose, and describes a modification in which one of the celluloid supporting layers carries an emulsion coating on either side. This subject-matter does not appear in the Specification as accepted.
