Abstract

847,143. Colour photographic materials. ILFORD Ltd. Oct. 31, 1958 [Nov. 18, 1957], No. 35919/57. Drawings to Specification. Class 98(2) Preparation of such materials involves mixing a silver halide emulsion containing a coloursensitising dye and a solution of a colour coupler or other compound, the tendency of which is to reduce the sensitivity of the emulsion at the site of a coating device and immediately coating on to a support immediately setting by chilling and rapidly drying to avoid the desensitising action of the coupler or other compound while the mixture is in the liquid state. Continuous feed into a mixing device and then to a coating device which avoids appreciable run-back of the mixture from the coating head or which extrudes the mixture on to the support is preferred. The method is particularly suitable for the red-sensitised layer of multilayer film, to which an example is directed, and a mixing device for the purpose is described and illustrated. Specification 625,992 is referred to.
