Abstract: Coated films and moulded articles of polyolefines are produced by subcoating the articles, whose surfaces have been pretreated with oxidising flames, oxidizing agents, by irradiation or by exposure to corona discharges, with polymers of ethylenically unsaturated polymerizable compounds, drying the subcoating, applying as top coating an aqueous dispersion of a copolymer of 80 to 97% by weight of vinylidene chloride and 3 to 20% by weight of another copolymerizable mono-olefine monomer and drying said top coating, wherein as subcoating there is applied an emulsion copolymer of 90 to 98% by weight of at least one polymerizable monoolefinic unsaturated compound and 2 to 10% by weight of at least one ethylenically unsaturated polymerizable N-alkylolamide compound. The N-alkylol-amide compound may be a N-methylolamide of a copolymerizable ethylenically unsaturated acid having three to five carbon atoms. The subcoating may be an emulsion copolymer of 90 to 98% by weight of at least one mono olefinic monomer selected from copolymerizable ethylenically unsaturated acids having three to five carbon atoms, their esters with alcohols having one to eight carbon atoms, their nitriles or amides, styrene, vinyl or vinylidene chloride, and vinyl esters of monocarboxylic acids having one to eighteen carbon atoms, and 2 to 10% by weight of at least one N-alkylolamide of a copolymerizable ethylenically unsaturated acid having three to five carbon atoms e.g. 90 to 98% by weight of at least one ester of a copolymerizable ethylenically unsaturated acid having three to five carbon atoms and an alcohol having one to eight carbon atoms and, possibly, at least one monomer selected from styrene, acrylic acid, methacrylic acid, acrylonitrile, and methacrylonitrile and 2 to 10% by weight of at least one N-methylolamide of a copolymerizable ethylenically unsaturated acid having three to five carbon atoms. The emulsion copolymer for the subcoating may have added to it 0.5 to 10% of its weight of at least one inorganic acid and/or organic acid and/or acid-reacting salts. The polyolefine may be a homopolymer or copolymer of monoolefins having 2 to 5 carbon atoms e.g. ethylene or propylene. The polyolefine may constitute a layer on a substrate e.g. nonwoven fabric, fabrics of natural and synthetic fibres, paper, cardboard, cotton cloth, and films or sheeting of semi-synthetic and synthetic materials. Solutions or dispersions of the copolymer of the subcoating may be applied by brushing, spraying, knife coating, rolling or trowelling.
