Abstract

511,574. Colour photography. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.). Feb. 18, 1938, No. 5138. [Class 98 (ii)] In printing multi-colour master images on to multi-layer material, there is used in addition to the normal white copying light, one or more additional coloured light sources, e.g., blue, green and red light sources, whereby colour faults are compensated. The necessary correction may be determined by a test development. The exposure material and printing material may be multi-layer material having several silver halide emulsion layers containing colour formers which are developed, directly or by reversal, by means of colour development, azocoupling or oxidation. Specifications 436,587. 458,400, 465,823, 468,946, 479,838, 481,501, 483,000, 484,698, 488,048, 488,853, 489,093, 489,161, 489,164, 489,274, 491,958, 491,959 and 492,523 are referred to.
