The invention relates to a method for the corrosion-inhibiting coating of metal surfaces, which in a first step involves cleaning the metal surface and optionally treating it with a pretreatment composition and in a second step involves coating the metal surface cleaned and optionally pretreated in step (1) with a primer (P) which comprises at least one binder (BM) and at least one crosslinking agent (V), and also at least one phosphorus-containing polyester component (A), (A) being an acidic esterification product of phosphonic acid, of monophosphoric acid and/or of polyphosphoric acid, and/or of the anhydrides thereof and/or of the esters thereof, with at least one polyester (B) which contains at least two hydroxyl groups. |
