Abstract

150,819. Greene, W. Friese-, and O'Malley, L. June 10, 1919. Colour photography.-In a colour process, two superimposed sensitive surfaces are exposed without a light filter, the front one being sensitized with an ordinary non-colour-sensitized emulsion and the rear one being sensitized by the coloursensitizing process described in Specification 134,238, to which Specification reference is made. The ordinary negative is used to obtain an orangepink positive and the other negative used to obtain a blue-green positive. The positives may be produced as transparencies for viewing or projection purposes, and the process is applicable for kinematography. Reference has been directed by the Comptroller to Specification 134,238.
