Colour photography. plates, films, and papers.-The negative component colour records are taken at a single exposure on compound sensitive material comprising in non-adhesive superimposition three layers having successively increasing speeds and different colour sensitivities, the layers being employed without colour filters, and preferably also having different densities. From these negative components, positive colour-record images are printed on compound sensitive material comprising three layers which print out in the desired colours, and require only washing after printing, and which are superimposed to produce the finished print. The negative material may comprise a strip of celluloid having three adjacent areas A, B, C, coated respectively with an ordinary 250 H. & D. emulsion for the blue component, an orthochromatic 400 H. & D. emulsion for the yellow component, and a red-sensitive or panchromatic 650 H. & D. emulsion for the red component, two of the coatings being on one side of the strip and the third on the other side. The emulsions are of increasing density from the blue to the red, and the strip is folded as shown in Fig. 2 to bring the coatings into superimposition, and is exposed in a camera with the slow emulsion nearest the lens. The strip is unfolded and developed, and prints are made from it upon positive material comprising three layers, preferably coated side by side on a common support, which may, for example, be layers prepared as described in Specification 280,252, and which print out respectively in yellow, red and blue. After washing and drying, the positive strip is folded to bring the component images into superimposition. The sections of either the negative or the positive material may be on separate supports, the final picture being produced in this case by superimposing the printed positives and binding them together at their edges.
