Abstract

330,735. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). May 17, 1929. Right to Patent relinquished. Coating-compositions are made by incorporating organic film-forming substances, or their solutions, with ketones having at least one aliphatic branched chain connected with the carbonyl group. Suitable ketones are iso-propyl ethyl ketone, iso-butyl ethyl ketone and their homologues; the neutral portions of the ketone mixture obtained by the action of carbon monoxide on benzine hydrocarbons according to Specification 310,438, [Class 2 (iii), Dyes &c.], may also be used. Drying oils, natural or synthetic resins, cellulose esters and ethers, bitumens, and solvents such as benzene hydrocarbons and alcohols may be added. Examples are (1) pyroxylin 50 parts, alcohol 50, ketone mixture of B.P. 110- 150‹ C., obtained by the process of Specification 310,438, [Class 2 (iii), Dyes &c.], 500, and benzene 400; (2) pyroxylin 100, colophony glycerine ester 20, dibutyl phthalate 40, ketone mixture of B.P. 100-150‹ C. 400, butanol 50, alcohol 100, benzene 200, toluene 50, and light benzine 40; (3) pyroxylin 50, colophony resin esters and cyclic ketone resins 100, tricresyl phosphate 10 to 20, ketone mixture of B.P. 100-150‹ C. 300, benzene 200, lithopone 37.5, and slate meal 37.5; (4) pyroxylin 50, dibutyl phthalate 10, castor oil 30, ketone mixture of B.P. 120-170‹ C. 500, toluene 300, light benzine 100; (5) ethyl cellulose 100, benzene 600, ketone mixture of B.P. 110-140‹ C. 100, toluene 150, and spirit 50; (6) proxylin 100, resin ester 100, linseed oil 100, ketone mixture of B.P. 100-170‹ C. 500, methyl acetate 100, toluene 100, and, optionally, gilsonite asphalt 25; (7) pyroxylin 100, tricresyl phosphate and colophony glyceryl ester 60 each, ketone mixture of B.P. 110-150‹ C. 250, butanol 50, commercial ethyl alcohol 100, toluene 150, xylene 180, and a mixture of equal parts of ethyl acetate, methanol and acetone 50; (8) resin prepared by heating colophony with phenol-formaldehyde condensation product 30, linseed oil 40, and benzine 30 are dissolved in the ketone mixture of Ex. 1; (9) pyroxylin 100, colophony glycerol ester 40, tricresyl phosphate 60, methyl iso-propyl ketone 600, and acetone 200. The methyl iso-propyl ketone may be replaced wholly or partly by methyl iso-butyl ketone or a mixture thereof with 20-50 per cent of cyclohexanine, butyl acetate, or propylene glycol mono-ethyl ether.
