Abstract

691,962. Colour photography. FRAUNHOFER, H. VON and COOTE, H. E. Jan. 5, 1949 [Dec. 5, 1947], No. 32148/47. Addition to 682,061. Class 98 (ii). The two-colour, three-colour effect, process of the parent Specification in which a twolayer negative having in one layer a magenta image of the red aspect of a subject and in the other layer a blue-green image of the bluegreen aspect of a subject is exposed through a greenish-yellow filter on to a two layer positive the upper layer of which has a red-sensitive silver halide emulsion containing a magenta colour former and the other layer of which has an orthochromatic silver halide emulsion containing a blue-green colour former, and which positive is colour developed and treated with a further colour former during development to selectively form a yellow deposit on the silver image in its magenta coloured layer, is modified by replacement of the red-sensitive magenta colour former layer of the positive with two half-thickness red-sensitive layers containing respectively a magenta and a yellow colour former, and this positive, after exposure is described in the parent Specification, is processed to produce in both the half-thickness layers an image corresponding to the red aspect of the subject. Processing may be as described for the negative material of the parent Specification.
