Abstract: 293,347. Schwickert Ges., R., and Burg, E. July 4, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Azo compounds; nitroso compounds.-The process of Specification 284,253, [Class 98 (ii), Photographic processes &c.], is modified by using as the light-sensitive media compounds produced by the action on diazo or nitroso bodies, such as diazotized 1-amino-2-naphthol-4-sulphonic acid, nitrosophenacetin, nitrosophenlactin, or aminophenol substituted by succinic acid, of alkali cr alkaline earth salts of aliphatic acids and oxyacids, aromatic carboxylic acids or sulpho acids, amido acids, &c., such as acetic, succinic, lactic, citric, tartaric, oxalic, benzoic, benzenesulphonic, cinnamic, and phenylacetic acids. The compounds are formed as precipitates by dissolving excess of the salt in a warm saturated aqueous solution of the diazo body or nitrosamine, and allowing to stand. Or concentrated solutions of the salt and of the diazo body or nitrosamine may be mixed together. Or, when a diazo compound is to be formed, it may be produced directly by diazotizing in a. solution of one of the aforementioned acids instead of in mineral acid, and neutralizing excess acid with alkali. To the lightsensitive layer may be added (1) hygroscopic substances such as alkali acetate or magnesium chloride, (2) acid salts such as alkali bisulphates, (3) substances such as organic acids to prevent coupling when coupling bodies are included in the layer, (4) oxidizing agents such as bichromates or alkali persulphates, perborates, and percarbonates, in order to deepen the colour of the pictures, and (5) catalysers to increase the effect of the oxidizing agents.

Abstract: 764,446. Photographic emulsions KODAK, Ltd. Jan. 21, 1955 [Jan. 25, 1954], No. 1942/55. Class 98(2) A silver halide emulsion is prepared by coagulating a dispersion of silver halide in an aqueous solution of an aromatic sulphonyl chloride, carboxylic acid chloride, carboxylic acid anhydride or aromatic isocyanate derivatives of gelatin by the addition to the dispersion while at a pH of not more than 10 a water-soluble salt (e.g. the chloride or nitrate) of cadmium, zinc, aluminium, iron, nickel, chromium or lanthanum, separating the granules of gelatin derivative containing silver halide, redispersing and performing a second coagulation if desired, and dispersing in a solution of gelatin or far-hydrolized cellulose acetate. The gelatin derivative may be a reaction product of gelatin with one of the compounds referred to in Specification 649,545 or with n - heptylsuccinic anhydride or hexahydrophthalic anhydride. A greater concentration of coagulating salt is required with an increase in pH and at a lower temperature. In Example 1, a silver iodochloride emulsion is prepared using a benzenesulphonyl chloride-gelatin derivatives as binder and is coagulated by addition of aqueous cadmium chloride at pH 6.3..After redispersion in water, the emulsion is again coagulated, and finally the coagulum is dispersed in aqueous gelatin and coated on to a cellulose acetate support. In Example 2, the procedure is similar chlorobromide emulsion, performing one coagulation only, and adjusting the pH of the final emulsion to 6.5 by the addition of aqueous NaoH solution. In Example 3, the procedure is similar to Example 2, using a silver iodobromide emulsion and the n-heptylsuccinc anhydride derivative of gelatin. In Example 4, the procedure is similar to. Example 3 using the hexahydroopthalic anhydride derivative of gelatin and coagulating with lanthanum nitrate. Specifications 649,544 '[Group IV(b)], 655,082 also are referred to.
