Abstract
506,331. Colour photography. GROVES, W. W. (I. U. Farbenindustric Akt.-Ges.) Aug. 25, 1937, No. 23315. [Class 98 (ii)] Coloured kinematograph films are produced by printing by imbibition from swollen gelatine reliefs, made by printing on bichromatcd gelatine layers from black and white positive component colour records produced by printing from a complementary coloured negative on multilayer material which has been exposed to the original and developed to colour. The colour formers may be present in the developer or in the sensitive material and in the latter case may be fast to diffusion. Suitable multi-layer films are described in Specifications 458,400, 465,823, 470,838, 483,000, 484,698, 489,093, 489,274, 491,958, and 491,959. Colour control copies may be produced by printing the negative on similar material and developing to a positive colour picture. A sound record may be printed on the final film by imbibition or in the form of a silver image or both may be superimposed. The sound record may also be printed by imbibition on the opposite side of the support using a dye solution containing a solvent for the material of the support.
