A composition for the treatment of metal surfaces and for the deposition of metals or metal alloys on plastics surfaces contains  b) water or another solvent which is suitable for dissolving, dispersing, suspending or emulsifying the polymer, as component B;c) if required, surface-active compounds, dispersants, suspending media and/or emulsifiers as component C. In a process for the treatment of a metal surface and a process for the deposition of metals or metal alloys on a plastics surface, the metal or plastics surface is brought into contact with a polymer (component A). Furthermore, polymers (component A) are used for the treatment of metal surfaces and for the deposition of metals or metal alloys on a plastics surface, and polymers composed of special components A'a, A&#x2032;b and A&#x2032;c.

A description is given of a microcapsule formulation comprising microcapsules having a core of a hydrophobic material and a capsule shell of an addition polymer containing in copolymerized form at least 1% by weight of cationogenic monomers and/or polyethylenically unsaturated monomers whose unsaturated sites are connected via successive chemical bonds of which at least one bond is acid-hydrolyzable. A description is further given of a microcapsule formulation comprising microcapsules having a core of a hydrophobic material, which comprises at least one fragrance or perfume, and a shell of an addition polymer containing in copolymerized form at least 1% by weight of anionogenic monoethylenically unsaturated monomers and/or polyethylenically unsaturated monomers whose unsaturated sites are connected via successive chemical bonds of which at least one bond is base-hydrolyzable. The microcapsule formulations are employed in laundry detergents or cleaning products.
