    Abstract: A composition for the surface treatment of metals and for the deposition of metals or metal alloys and plastics surfaces comprises a) at least one polymer as component A, comprising at least one structural unit of the formula (I) where this structural unit may be part of a polymer main chain or may be bound to a polymer main chain via an anchor group, and M is hydrogen or an ammonium or metal cation; b) water or another solvent which is suitable for dissolving, dispersing, suspending or emulsifying the polymer (component A), as component B; c) if required, surface-active compounds, dispersants, suspending media and/or emulsifiers as component C; either d) if required, a salt, an acid or a base based on transition metal cations, transition metal oxoanions, fluorometallates or lanthanoids as component D, and/or e) at least one acid selected from the group consisting of phosphoric acid, sulfuric acid, sulfonic acid, nitric acid, hydrofluoric acid and hydrochloric acid as component E, or a base and/or f) at least one metal oxide and/or metal salt as component F. Furthermore, in a process for the surface treatment of metals and in a process for the deposition of metals or metal alloys on a metal surface or plastics surface, the metal surface or plastics surface is brought into contact with a polymer (component A). Moreover, polymers (component A) are used for the surface treatment of metals and for the deposition of metals or metal alloys on a metal surface or plastics surface.

    Abstract: The invention relates to a composition for treating the surfaces of metals a nd for depositing metals or metal alloys on plastic surfaces. Said composition contains: a) at least one polymer, as constituent A, containing at least one structural unit of formula (I), wherein said structural unit can be part of a polymer main chain or can be bound to a polymer main chain by means of an anchor group, and M is hydrogen or an ammonium cation or a metal cation; b) water or another solvent, as constituent B, which is suitable for dissolving , dispersing, suspending or emulsifying the polymer (constituent A); c) optionally surface-active compounds, dispersants, suspension agents and/or emulsifying agents as constituent C; and either d) optionally a salt, an aci d or a base based on transition metal cations, transition metal oxoanions, fluorometallates or lantanoids as constituent D, and/or e) at least one acid selected from the group consisting of phosphoric acid, sulphuric acid, sulfonic acid, nitric acid, hydrofluoric acid and hydrochloric acid as constituent E, or a base, and/or f) at least one metal oxide and/or metal sa lt as constituent F. The invention also relates to a method for treating the surfaces of metals, and to a method for depositing metals or metal alloys on a metallic or plastic surface, wherein the metallic or plastic surface is brought into contact with a polymer (constituent A). The invention further relates to the use of polymers (constituent A) for treating the surfaces of metals and for depositing metals or metal alloys on a metallic or plastic surface.
