Abstract
458,400. Colour photography. GROVES, W. W., 30, Southampton Buildings, Chancery Lane, London.-(I. G. Farbenindustrie Akt.-Ges. ; Frankfort-on-Main, Germany) April 13, 1935, No. 11502. [Class 98 (ii)] In a process for producing by development coloured pictures in silver halide emulsion layers, a substance is present in the layer derived from a body capable of coupling with a developer oxidation product to produce a colour, by the introduction into the body of a group which imparts to it a substantive character with respect to the binding agent of the emulsion, so that it does not diffuse out of the layer. Compounds referred to as capable of coupling with a developer oxidation product are phenols, naphthols, aniline, naphthylamine, and aminonaphthols, and compounds containing reactive methylene groups such as acetoacetic esters, cyanoacetic esters, benzoylacetic esters, hydrindene, pyrazolones, and coumaranone. Groups specified for imparting a substantive character are the radicals of diphenyl, stilbene, azoxybenzene, oxynaphthoic acid amide, diarylureas, benzthiazole, certain phenols substituted in 3 : 5 position, and aminophenols. A multilayer film comprises the following layers arranged on one or both sides of the support ; p - - (oxynaphthoylamino) - 1 - phenyl - 3 - methyl-5-pyrazolone for red; terephthaloylbisacetic acid anilide for yellow; 3: 5-di- (phenylamino )-phenol for blue-green. The alkali salts of these compounds, dissolved in methanol, are stirred into 10 per cent. gelatine solution, and the mixture is mixed with silver halide emulsion. The developer comprises diethylaminoaniline hydrochloride and potassium carbonate, with or without sulphite. Specifications 15055/12 and 2562/13, [both in Class 98 (ii)], and 365,531, 403,915, 415,945, and 417,936, [all in Group IV], are referred to.
