ABSTRACT:
The present invention relates to a composition for treating surfaces, comprising a copolymer as component A, synthesized from (meth)acrylic acid or salts thereof, a carboxylate-containing monomer and/or monomers containing groups containing phosphoric and/or phosphonic acid or salts thereof, and further comonomers if desired, to a passivating layer on a metal surface, which comprises component A, to a process for forming said passivating layer, and to the use of the composition of the invention to passivate a metal surface.
