    Abstract: Release coating compositions for coating tapes and sheets (see Group VIII) comprise (1) a tough and fiexible film-former agent which is a synthetic or modified natural polymeric material and is self-adhesive to said tape or sheet, and (2) a monomeric waxy release agent which has a melting point above 200 DEG F. and is an N, N1-alkylene bis amide of a fatty acid or a hydrocarbon wax. Specified film-former agents are nitro-cellulose, polystyrene, polyvinyl acetate, polyvinyl chloride, vinyl chloride-vinylidene chloride copolymers and vinyl chloride-vinyl acetate copolymers. Specified release agents are N, N1-methylene bis stearamide and N, N1-ethylene bis stearamide. The compositions may also comprise plasticizers, e.g. polyesters, tricresyl phosphate and dioctylphthalate, pigments and stabilizers, and may be applied from solutions or dispersions in volatile solvents, such as ketones, octane or xylene. Specification 689,667 is referred to.

    Abstract: 368,199. Adhesive tape. KODAK, Ltd., Kodak House, Kingsway, London.- (Assignees of Dow, E. M. ; Kodak Park, Rochester, New York, U.S.A.) Aug. 26, 1931, No. 24003. Convention date, Aug. 29, 1930. [Class 140.] Adhesive tape comprises a cloth, paper or like support coated on one side with an adhesive, and on the other side with a composition containing an acyl ester of cellulose having less than six carbon atoms in the acyl group, preferably cellulose acetate. Any type of adhesive may be used, for example, that commonly used in the production of medical adhesive tape. The cellulose ester composition may contain cellulose acetate, a plasticizer, for example diethyl phthalate, triphenyl or tricresyl phosphate, or monochlor-naphthalene, and a solvent such as acetone and ethyl lactate, or acetone, a high boiling solvent, and a diluent. In place of cellulose acetate, cellulose propionate or cellulose butyrate may be used. Smooth paper, cloth or other fabric, or corrugated, crinkled or otherwise deformed paper or cloth may be used as the support. Specification 348,694 is referred to.
