Abstract
Method of applying corrosion control coats, especially integrated pretreatment layers or coats for atmospheric corrosion control, to metallic surfaces, using copolymers comprising as monomeric building blocks 20% to 70% by weight of monomers containing nitrogen heterocycles, 10% to 50% by weight of monomers containing acidic groups, 10% to 50% by weight of vinylaromatic monomers, and optionally 0% to 25% by weight of further monomers. Copolymers of the stated composition, and also preparations for applying corrosion control coats.
