Abstract
685,612. Colour photography. GANGUIN, K. O. HADDOCK, N. H., MACDONALD, E., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 23, 1950 [Feb. 23, 1949], No. 4918/49. Drawings to Specification. Class 98 (ii). A multilayer false colour transparency carrying colour photographic records in yellow, magenta and cyan dyestuff in three separate layers as described in Specification 685,607 is provided with a yellow styryl dyestuff masking image in the magenta layer as by the method of Specification 651,059 instead of the black and white masking images of Specification 685,607. This masked false colour record is printed on to a corresponding false colour material which has colour formers in the layers and the latter is processed to provide a colour corrected print or transparency. Specifications 486,848 and 489,162 also are referred to.
