| abstract | 552. Fox, W. F., Hickey, W. H., and Kinemacolor Co. Jan. 8. Right to Patent relinquished. Colour photography.-A process for obtaining colour photographs or colour kinematograph films comprises the following steps: (1) taking two identical or closely similar images through a red and green screen respectively, for example successive R and G images of a kinematograph negative film, Fig. 1; (2) printing a positive B, Fig. 2, of these images; (3) superposing the negatives and positive images so that an R negative is superposed on the corresponding G positive image and vice versa, and using this as a combination negative to obtain a printing- negative C, Fig. 4, only alternate pairs of the combination negative being used for obtaining the printing-negative in the case of kinematograph negatives in which the R and G images are taken alternately; (4) producing a positive D, Fig. 5, from this printing-negative; (5) subjecting this positive first to an acid green bath, and after washing to an alkaline red bath, or alternately first to a bath of vanadium chloride to make the silver deposit on the film absorptive, then to a green bath, and subsequently to an alkaline red bath. To obtain a better graduation and blend of colours, the following additional steps may be taken: recoating the positive either on the front or back, printing in register and successively the two component images in the negative A, and developing these images so printed. Alternatively, and as may be required, only one of these images can be printed. Alternatively and where copies are not required, the printing-negative C can be coloured and further treated as in step 5 described above. Reference has been directed by the Comptroller to Specification 7368/13. |
