<p>A coating composition comprises a vinyl chloride-vinyl acetate copolymer plasticised by an alkyl ether alcohol ester of an aliphatic dicarboxylic acid having four to nine carbon atoms in the straight chain. It is preferred to use a resin containing 90 to 95 per cent vinyl chloride. Specified plasticisers are the azelaic, suberic, pimelic, glutaric, adipic, succinic and tartaric, diesters of monobutyl ether of ethylene glycol. The monobutyl ether of ethylene glycol radical may be replaced by the methyl, ethyl or propyl ether of ethylene glycol, by the methyl, ethyl, butyl or propyl ether of diethylene glycol, or by the methyl, ethyl, butyl or propyl ether of propylene glycol. The examples disclose vinyl chloride-vinyl acetate copolymers containing pigments, methyl ethyl ketone and (1) the azelaic diester of monobutyl ether of ethylene glycol and a stabilizer (2) and (3) the suberic diester of the monobutyl ether of ethylene glycol and phenoxy propylene oxide and (4) the azelaic diester of monobutyl ether of ethylene glycol and phenoxy propylene oxide and (5) the glutaric diester of monobutyl ether of diethylene glycol. The composition may be used for all normal coating purposes, particularly for the coating of fabrics. Such fabrics may have several coatings of the composition and may be laminated. A coated fabric may be further treated by embossing the coating by pressing the material between heated embossing rolls, one of which is steel and has a design engraved thereon. U.S.A.
