Abstract: A process for coating plastic or metal surfaces by 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 those ethylene copolymers which contain, copolymerized as comonomers, (a) from 15.5 to 19.9% by weight of at least one ethylenically unsaturated C3-C10-carboxylic acid and (b) from 80.1 to 84.5% by weight of ethylene, (B) at least one base, in one step and subsequently providing the plastic or metal surface in question with at least one further layer in at least one further step.
