Abstract
1,008,013. Colour reversal processes; colour developers. ILFORD Ltd. Feb. 14, 1964 [Feb. 26, 1963], No. 7765/63. Heading G2C. In a photographic colour reversal process wherein the residual silver halide is rendered developable by treatment with an alkali metal borohydride (see Specification 904,462), the borohydride is added to the colour developing solution. The invention may be used for the reversal of colour material in which the colour couplers are incorporated into the layers of the material. Where the colour couplers are not included in the material, the layers are selectively reexposed and developed in a colour developer containing the appropriate colour coupler in the usual way, except that the re-exposure of the last layer (e.g. the green-sensitive middle layer) is omitted, and an alkali metal borohydride is added to the final colour developer (containing the magenta colour coupler).
