Title: Improvements relating to photographic printing
IPC: G03C7/18
Filed: 1935-05-29
Abstract: 460,653. Colour and stereoscopic photography. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) May 29, 1935, No. 15637. [Class 98 (ii)] Coloured prints on a multilayer film are produced from a set of component pictures, especially colour component pictures, by first printing the component pictures on a single intermediate lenticular or multicolour screen film and then printing the component pictures on this film on to the multilayer film. The component pictures may be printed on to a lenticular film by contact printing as described in Specification 392,987 or by projection printing, or may be printed on to a multicolour screen film by contact printing with filters, or by projection printing with filters as described in Specification 390,327. The colours on the intermediate film need not correspond with those of the original. The layers of the multilayer film are differently sensitized and the intermediate film is printed thereon through suitable filters. The layers may contain dyestuffs, or may be subsequently coloured. With films having two layers on one side of the support and one on the other, the process of the invention is applied only in respect of the two superimposed layers. In one example, the blue and green components are printed with red and blue filters respectively on to a two-colour (blue and red) screen film, which is printed by white or purple light on to the red-sensitive yellow layer and the blue-sensitive purple layer of a three-layer film. An intermediate positive of the red-component negative is printed on to the blue-green layer on the other side of the support. In another example, two stereoscopic negatives are printed on to a lenticular film, which is then printed with red and green filters on to a two-layer film having superimposed redsensitive red and blue-sensitive blue-green layers. In another example, the lenticular film of a lenticular bi-pack, Specification 395,124, is developed to a positive by the reversal process, and printed on to a lenticular film by contact. The rear film is printed with its image layer towards the sensitive layer of the intermediate film. The intermediate film is printed by contact on to a multilayer film similar to that of the first example, using red or yellow and blue or blue-green filters. During printing, the lenticular film may be curved, or a lens may be arranged against the lenticular surface. In a modification, an intermediate multicolour screen film may be used, the printing being as described in Specification 353,121.

Title: Improvements in the production and use of solutions of acrylonitrile polymers
Inventor: HODGE EDWARD WILLIAM WHEATLEY
IPC: C08J3/02
Filed: 1951-07-02
Abstract: Polyacrylonitrile and copolymers containing a preponderating proportion of acrylonitrile are dissolved in a solvent mixture of nitric acid, water, and an organic liquid which is itself a solvent or swelling agent for polyacrylonitrile and which is resistant to attack by the nitric acid in the mixture, such as nitromethane, nitroethanol, or dimethyl formamide, the amount of nitric acid in the mixture being 1 to 9 times the weight of the water.  Copolymers of acrylonitrile specified are those with vinyl acetate, beta-morpholinoethyl vinyl ether, styrene, methyl and phenyl acrylates, methacrylonitrile, vinyl and vinylidene chlorides, 2-vinyl pyridine, and 2-methyl-5-vinyl pyridine The nitric acid in the solvent exerts a hydrolytic action on the polymers which converts amide to nitrile groups, thus improving the affinity of the polymers for dyes; the degree of hydrolysis is controlled by the concentration of the nitric acid, and the temperature of the solution and the time for which it is kept before use.  The solutions may be used in the preparation of films and fibres by extruding or casting into coagulating baths, such as aqueous solutions of sodium or ammonium nitrate or hydroxide, aqueous solutions of nitric acid of 5 to 36 per cent concentration, nitromethane, or carboxylic acid esters as described in Specification 712,984.  The solutions may also be used in the production of coatings.  Specification 636,476 also is referred to.  The Provisional Specification describes also the use of nitric acid as a solvent for acrylonitrile polymers, preferably in 45 to 90 per cent concentration in water, and also the use in conjunction with the nitric acid of 1,2,4-triazole and 4-amino-1,2,4-triazole, alone or mixed with nitromethane.
