Abstract

Aqueous polymer dispersions based on copolymers of C.sub.2 -C.sub.14 olefins and monomers which contain acidic functional groups or are able to form them by hydrolysis, which dispersions may also contain colorants and/or corrosion inhibitors dispersed or dissolved in the polymer phase, are used for protecting metallic surfaces against corrosion.
