Abstract
850,390. Resin dispersions, finishing and coating leather. IMPERIAL CHEMICAL INDUSTRIES Ltd. Feb. 10, 1958 [April 26, 1957], No. 13337/57. Classes 76 and 140. Leather is finished by treatment, e.g. by padding and/or spraying with a plasticized aqueous dispersion of a polymer or co-polymer of at least one acrylic or methacrylic ester, the plasticizer used containing a sulphonamide group and thereafter treating with formaldehyde. Stabilizers and emulsifiers e.g. longchain sulphates or sulphonates, soaps, ethylene oxide condensates; colloidal stabilizers, e.g. casein, gums, starches, polyvinyl alcohol; other known adjuvants, e.g. pigments, dyestuff solutions, wax emulsions and minor amounts (less than 50% by weight) of other polymerizable ethylenically unsaturated monomers, e.g. vinyl esters, styrene, butadiene, acrylamide and methacrylamide may be included in the dispersion. Specified esters are the methyl, ethyl, propyl, butyl, #-ethoxyethyl and nonyl esters of acrylic and methacrylic acids. Specified plasticizers are the N-ethyl-toluenesulphonamides.
