Abstract

1,160, 524. Black and white and colour photographic materials. EASTMAN KODAK CO. June 28, 1966 [June 28, 1965], No.28849/66. Heading G2C. A photographic material comprises a support, a first light-sensitive system comprising at least one light-sensitive silver halide emulsion layer containing a colour coupler forming a coloured substance and a second light-sensitive system comprising a silver halide emulsion layer which is sensitive to a part or the whole of the region of the spectrum to which the first system is sensitive e. g. a panchromatic emulsion layer and which has either a greater or less sensitivity to said part or whole than the first system and which contains a colour coupler or mixture of colour couplers capable of forming substances which produce a visual neutral colour or which protect the silver image produced by the developing agent from the action of silver bleaching agents. If the second system is faster over-exposure will necessitate black and white development bleaching and fixing before colour development to remove an overall black colour. The first system may be a multi-colour system. Many couplers and coupler combinations are listed.
