Abstract: The invention relates to a method for coating metallic surfaces with a copolymer of olefins and/or dienes, acid monomers and optionally other monomers. According to said method, the metallic surfaces are contaminated by an oil and/or fat which is not removed before the coating. The invention also relates to metallic surfaces that can be obtained by means of the inventive method.
