A method for anti-corrosive coating of metal surfaces using phosphorus-containing low molecular weight compounds

The invention relates to a method for anti-corrosive coating of metal surfaces, wherein in a first step, the metal surface is cleaned and is optionally treated with a pretreatment agent and in accordance with step (1) purified and optionally pretreated metal surface with a primer in a second step (P) is coated which contains at least one binder (BM) and at least one crosslinking agent (V), and a component (a), wherein (a) an acidic ester of phosphonic acid, mono phosphoric acid and / or polyphosphoric acid, in particular polyphosphoric acid, or of their anhydrides and / or their esters, and at least one compound (B) having at least two hydroxyl groups, is.
