Abstract

483,035. Colour photography. TRUECOLOUR FILM, Ltd., DOLGORUKI, E. SANDERS-, and REINDORP, J. H. Oct. 9, 1936, No. 18759/37. Divided out of 483,020. [Class 98 (ii)] A photographic material for the production of multicolour photographic records comprises a support carrying three super imposed silver halide emul sion layers sensitized to diff erent spectral regions, and thin filter layers between the emulsion layers, which filter layers are capable of preventing the passage of light of a given spectral composition and of remaining unaffected by at least some of the reagents used in the processing of the exposed material, and which can be rendered substantially transparent to white light or light of the given spectral composition by treatment in a reagent incapable of affecting substantially a colour-developed image. As shown, the material comprises a celluloid or paper base 1, with blue, red and green (or blue, green and red) sensitive emulsion layers 2, 3, 4 and intermediate filter layers 5 coloured vellow with the free base of Auramine. The emulsion layers may contain restraining filter dyes. An antihalation layer 6 comprises a colloid layer containing neutral carbon black or a water soluble black dyestuff. The filter layers are decolorized by dilute acid, for example acetic acid, solution. Specifications 444,198, 446,234, and 447,748 are referred to.
