Abstract: Lacquers, varnishes, plastic masses, filaments, films, and like materials from cellulose esters and ethers, natural and synthetic resins comprise as solvent, or softening agent a monoether of glycerine or polyglycerine with an aliphatic alcohol containing not less than eight carbon atoms or a cycloaliphatic alcohol, or an ester obtained from such an ether by esterifying free hydroxyl groups with organic acids.  The ethers may be obtained by reacting alkyl sulphonic acids with glycerine or a polyglycerine in an alkaline medium.  Ethers of dodecyl-, myristyl-, cetyl-, octadecyl-, myricyl-, oleyl-, and ricinoleyl alcohols and of naphthene alcohols are specified.  The lacquer or film base may be cellulose acetate or nitrate, ethyl cellulose, colophonium, copal, resin ester, or a glyptal resin.  In an example, cellulose nitrate moistened with methylated spirit is dissolved in butyl acetate containing dodecyl glycerine ether acetate, Albertol resin, and toluene to form a lacquer.  In another example. acetylcellulose is dissolved with octyl glycerine ether in ethyl lactate, acetone, alcohol, and benzene to form a lacquer.  Another lacquer comprises ethyl cellulose, alcohol, benzene, and cyclo hexyl glycerine ether or an ether of glycerine with the alcohols obtained by reduction of naphthenic acid.  Cetyl glycerine butyrate, adipate, benzoate, and hydrophthalate are also specified.  In another example, a lacquer is made of nitrocellulose, diglycerine cetyl ether, dammar resin, blown castor oil, toluene, alcohol, and acetone.  In another example, nitrocellulose, diglycerine octadecyl ether, and triphenyl phosphate are worked in a kneading machine and the mass is rolled into sheets.ALSO:Lacquers, varnishes, and like materials from cellulose esters and ethers, natural and synthetic resins comprise as solvent, or softening agent a monoether of glycerine or polyglycerine with an aliphatic alcohol containing not less than eight carbon atoms or a cycloaliphatic alcohol, or an ester obtained from such an ether by esterifying free hydroxyl groups with organic acids.

In an example, cellulose nitrate moistened with methylated spirit is dissolved in butyl acetate containing dodecyl glycerine ether acetate, Albertol resin, and toluene to form a lacquer.  In another example acetyl-cellulose is dissolved with octyl glycerine ether in ethyl lactate, acetone, alcohol, and benzene to form a lacquer.  Another lacquer comprises ethyl cellulose, alcohol, benzene, and cyclo hexyl glycerine ether or an ether of glycerine with the alcohols obtained by reduction of naphthenic acid.

In another example, a lacquer is made of nitrocellulose, diglycerine cetyl ether, dammar resin, blown castor oil, toluene, alcohol, and acetone.ALSO:Plastic masses containing natural and synthetic resins comprise as solvent, or softening agent a mono-ether of glycerine or polyglycerine with an aliphatic alcohol containing not less than eight carbon atoms or a cycloaliphatic alcohol, or an ester obtained from such an ether by esterifying free hydroxyl groups with organic acids.  Ethers of dodecyl-, myristylcetyl-, octadecyl-, myricyl-, oleyl-, and ricinoleyl alcohols and of naphthene alcohols are specified.  The plastic material may contain cellulose acetate or nitrate, ethyl cellulose, colophonium, copal, resin ester, or a glyptal resin.
