Abstract

503,832. Colour photography. I. G. FARBENINDUSTRIE AKT.-GES. Sept. 10, 1937, No. 24725. Convention date, Sept. 15, 1936. [Class 98 (ii)] In the production of kinematographic multicolour pictures there is produced in addition to the main original, a proof original on photographic material having several silver halide emulsion layers containing colour formers fast to diffusion and which are processed by colour development, the proof original being used to edit the main original. The emulsion layers and the process of development are as described and claimed in Specifications 458,400, 465,823, 479,838, 483,000, 484,698, and 488,853. The proof originals may be developed directly to positives by reversal development or developed and printed by the negative-positive process.
