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.
