Abstract

1441. Eichengr³n, A. Jan. 25, 1909, [Convention date]. Coating-compositions. - Acetyl-cellulose solutions are produced by treating suitable acetylcelluloses, particularly such as are soluble in acetone or acetic ether, with a hot solvent mixture, of liquids which individually are not solvents either when hot or cold. Camphor or camphor substitutes can be added to the solutions, homogeneous masses being thereby obtained. Liquids which are solvents of acetylcellulose in the cold may be added at any stage. Fabrics &c. may be coated with the acetylcellulose masses. In one example, a mixture of alcohol and benzene is used as the solvent mixture, and in a second example a mixture of methyl alcohol and toluene. Other homologues and substituted derivatives of benzene and alcohol may be used and either of the latter liquids may be wholly or partially replaced by others which are themselves non-solvents. The Specification as open to inspection under Section 91 (3) (a) comprises also the addition of colouring-matters to the solutions, and the production of various effects by addition of resins, and mineral substances such as zinc white, graphite, mica, asbestos, or powdered metal. This subject-matter does not appear in the Specification as accepted.
