Beschreibung
Zusammenfassung:	The invention relates to an aqueous coating agent for metal substrates, containing a water-dispersible and/or water-soluble polymer (P) with covalent bonded ligands (A), forming chelates with the metal ions released on corrosion of the substrate and/or the substrate surface and with cross-linking functional groups (B) which can form covalent bonds with themselves, with further complementary functional groups (B') of the polymer (P) and/or with further functional groups (B) and/or (B') on cross-linkers (V). L'invention concerne un agent de revêtement aqueux destiné à des substrats métalliques et contenant un polymérisat P dispersible et/ou soluble dans l'eau. Ce polymérisat porte des ligands A à liaison covalente qui forment des chélates avec les ions métalliques libérés lors de la corrosion du substrat et/ou avec la surface du substrat, ainsi que des groupes fonctionnels B à effet réticulant qui peuvent former des liaisons covalentes avec eux-mêmes, avec d'autres groupes fonctionnels complémentaires B' du polymérisat P et/ou avec d'autres groupes fonctionnels B et/ou B' sur des agents de réticulation V.
