Abstract

317,871. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). May 21, 1928. Transfers; transferring designs. - In transfers for applying designs, wood or marble graining, pictures, trade marks, advertisements, &c. to glass, wood, metal, or other materials, either directly or on a coating of lacquer or paint, the transferable layer coming into contact with the surface to be decorated is an adhesive layer containing cellulose derivatives, and, if desired, resins which are both soluble in alcoholic solvents. This layer may be the design layer or a transparent or opaque coloured layer which forms a background for the design when applied. Before applying the design to the transfer paper, the paper may receive a coating of a composition containing cellulose derivatives, which coating forms a protective coating for the design when applied to the surface to be decorated. The transfers are particularly suitable for application to cellulose lacquers substantially insoluble in alcohol such as those used for lacquering motor cars, and the transfer is effected by wetting the surface of the transfer with alcohol and applying by pressure. In one example, the transfer paper is printed with a design in an ink consisting of 15 parts of an alcohol-soluble nitrocellulose, 9 parts of tricresyl phosphate, 3 parts of castor oil, 7.5 parts of resin soluble in alcohol, 15.5 parts of an organic or inorganic pigment or metal powder, 10 parts of alcohol, 20 parts of ethylene glycol mono-methyl ether, and 20 parts of ethylene glycol mono-ethyl ether. In another example, the transfer paper is first provided with a coating composition consisting of 160 parts of cellulose ethyl ether, 25 parts of tricresyl phosphate, 15 parts of triphenyl phosphate, 30 parts of castor oil, 20 parts of colophony esterized with glycol, 400 parts of xylene, 200 parts of butanol, and 150 parts of ethylene glycol mono-ethyl ether. Upon this layer the design is printed in oil colour or in an ink consisting of 150 parts of nitrocellulose, 70 parts of tricresyl phosphate, 30 parts of triphenyl phosphate, 65 parts of milor blue, 35 parts of colophony esterified with glycerol, 150 parts each of xylene and of butanol, and 350 parts of acetate of ethylene glycol mono-ethyl ether. A covering layer of lacquer consisting of 200 parts of an alcohol-soluble nitrocellulose, 100 parts of dibutyl phthalate, 50 parts of colophony, 200 parts each of ethyl alcohol and ethylene glycol mono-ethyl ether, and 250 parts of acetate of ethylene glycol mono-ethyl ether is then applied. The design may be printed on the transfer partly in opaque and partly in transparent colours if desired.
