Abstract: Removable protective film (A) on a surface comprises at least a polymer (70 wt.%), based on the total quantity of all the components of the layer, containing at least two different polymers containing ethene (65 wt.%), where (A) is bounded with oxygen bonded carbon and the oxygen content of (A) increases with the increase in the distance to the surface. An independent claim is included for a method for applying (A) on a surface comprising treating the surface with n aqueous formulation (F i) of polymers (where n is >= 2 and i is 1 to n) comprising at least one ethene (65 wt.%) exhibiting oxygen bonded carbon; where the oxygen is optionally bonded to either polymer or to additional components of the formulation and the content of the oxygen bound to carbon in F iincreases with the increase in i.

Abstract: Passivating layer (I) on a metallic surface is prepared by contacting the surface with a composition comprising a water-soluble, nitrogen-containing polymer that is a base, whereby an aqueous solution of the polymer forms a precipitate at the metal surface upon addition of one or more metal salts at a pH of less than 7. Independent claims are included for: (a) metallic surfaces having the passivating layer (I); (b) a construction (II) comprising a metallic surface, the passivating layer (I) and further paint layers and; (c) a process for the formation of the construction (II) by formation of the passivating layer (I) on the metallic surface followed by painting.

Abstract: A composition for the treatment of metal surfaces and for the deposition of metals or metal alloys on plastics surfaces contains a) at least one polymer as component A, composed of the structural element (1) and at least three structural elements selected from the group consisting of 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'b and A'c.
