Abstract

151,014. Amiot, J. Sept. 15, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Plates, films, and papers; sensitive coatings, preparing.-A sensitive preparation for enabling any surface to be sensitized by a single cold paint. ing or application is obtained by the addition to a solution of a soluble silver salt of a colloid or a mixture of colloidal matter in proportions suitable for stopping the imbibition of the product by the surface while leaving it fluid at the ordinary temperature. A solution of acid citrate or silver is mixed with a solution of caseinate of soda and to the mixture is added a suitable proportion of gelatine. A small quantity of resorcin may also be added and gives various tints to the printed positive.
