Abstract

486,517. Kinematograph colour and sound films. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Sept. 3, 1936, No. 24147. [Class 98 (ii)] In producing kinematograph films having a multi-colour picture record and a sound record, material carrying several differently sensitized silver halide emulsion layers containing colour formers fast to diffusion is exposed to record the sound in one or more layers and the sound record is treated in the same operation as the picture record to produce by the synthesis of dyestuff a sound track in colour. The sound record may be produced in one or more of the emulsion layers by colour development or the azo-coupling method, and the emulsion layers may contain colour formers fast to diffusion. The sound record may be produced by exposure or copying, and according to the colour of the light used may be produced in one or several layers. The picture and sound records may be developed by the normal method or by reversal. Specifications 436,587, 458,400, 465,823, 468,946, 476,672, 479,838, and 481,501 are referred to.
