Abstract

655,344. Colour photography. PAPADAKIS, S. Aug. 26, 1947, No. 23513. Convention date, Nov. 11, 1943. [Class 98 (ii)] Three positives are copied from three negative colour records, one positive is toned to its appropriate colour, and the other two colours are applied successively to this by sensitizing with bichromate, exposing through another positive, washing and colouring with a corresponding dye, the second of the two sensitizing baths being more concentrated than the first, or the second exposure being longer or more intense than the first. Iron, copper or uranium toning may be used.
