Abstract
592,245. Reflex printing; colour photography. KODAK, Ltd., and STEVENS, G. W. W. March 7, 1945, No. 5666. [Class 98 (ii)] Three-colour-separation records are made by reflex printing from a multi-coloured picture or drawing on to three different portions of a sensitive material consisting of a support bearing a silver chloride emulsion of the gaslight type sensitized to blue, green and red by the use of blue, green and red light respectively. When the emulsion is coated on a transparent support such as film or glass plates, a lightscattering undercoat layer, as described in Specification. 529,041 is necessary, and the pigment for this undercoat should be insensitive and photographically innocuous and should not absorb heavily in the region 400-480 mÁ. The pigment may be such as can be removed during processing.
