Abstract: A method of coating surfaces of plastic or metal, which comprises treating the plastic or metal surface in question with an aqueous dispersion comprising (A) at least one ethylene copolymer having a molecular weight Mn in the range from 2000 to 20 000 g/mol, selected from ethylene copolymers comprising as comonomers in copolymerized form (a) 15.5% to 19.9% by weight of at least one ethylenically unsaturated C3-C10 carboxylic acid and (b) 80.1% to 84.5% by weight of ethylene, (B) at least one base, in one step and subsequently providing in at least one further step the metal or plastic surface in question with at least one further coat.
