    Abstract: A composition for the treatment of metal surfaces comprises 50-99.9 wt.% (meth)acrylic acid or its salts, 0.1-50 wt.% of a carboxylate containing monomer or corresponding salts, anhydrides or esters and/or 0.1-50 wt.% monomers containing phosphoric and/or phosphoric acid groups or their salts, 0-30 wt.% of other compatible monomers and water or another solvent suitable for the dispersion, suspension or emulsification of monomers. A composition (I) for the treatment of metal surfaces comprises: (a) 50-99.9 wt.% (meth)acrylic acid or its salts, 0.1-50 wt.% of a carboxylate containing monomer of formula (1) or corresponding salts, anhydrides or esters and/or 0.1-50 wt.% monomers containing phosphoric and/or phosphonic acid groups or their salts, 0-30 wt.% of other compatible monomers; (b) water or another solvent suitable for the dispersion, suspension or emulsification of (A) and optionally; (c) other surface active agents, dispersing agents, suspending agents and/or emulsifiers. [Structure 1, p46] (1) n : 0-10; R 1>, R 2>,R 3>H, 1-18C alkyl, 3-6C cycloalkyl, 2-18C alkenyl, 3-6C cycloalkenyl, 6-12C aryl optionally substituted by alkyl or aryl whereby R 1>-R 3> are optionally substituted by a carboxyl group; R 4>,R 5>H, 1-18C alkyl, 3-6C cycloalkyl, 2-18C alkenyl, 3-6C cycloalkenyl, 6-12C aryl optionally substituted by alkyl or aryl Independent claims are included for: (1) a passivating layer on a metal surface prepared by contacting the metal surface with the component (A); (2) the resulting passivated metal surface and: (3) a structure prepared by application of further coating layers onto the passivated metal surface.
