ABSTRACT:
The present invention relates to a passivating layer on a metal surface, obtainable by contacting the metal surface with a composition comprising a water-soluble nitrogenous polymer, to a surface composed of a metal surface and the passivating layer of the invention, to a process for forming a passivating layer on a metal surface, to the use of a composition comprising a water-soluble nitrogenous polymer to passivate a metal surface, and to a system on a metal surface that comprises a passivating layer of the invention and further coating films.
