Abstract

822,231. Dressing leather. FARBENFRIKEN BAYER A.G. June 30, 1958 [July 1, 1957], No. 20931/58. Classes 76 and 140. Leather is dressed with dispersions of polymers containing carboxylic acid groups in the presence of a zinc compound. Suitable dispersions are those obtained by copolymerization of esters of acrylic or methacrylic acid, such as the methyl, ethyl, butyl or octyl esters, with vinyl chloride, vinylidene chloride, styrene, butadiene, vinyl alcohol derivatives, vinyl ethers, acrylonitrile, methacrylonitrile, acrylic acid amide, methacrylic acid amide, alkylvinyl ketones, arylvinyl ketones, vinyldicarboxylic acid esters such as diethylfumaric acid ester, or divinyl compounds such as divinyl benzene, or mono-functional and polyfunctional vinyl carboxylic acids such as acrylic acid, methacrylic acid, fumaric acid, maleic acid and hemi-esters of these dicarboxylic acids. Suitable zinc compounds are finely divided zinc oxide, zinc hydroxide or water-soluble zinc salts such as zinc acetate. The zinc compound should be used in a quantity at least equivalent to the free carboxylic acid groups of the polymer dispersion used.
