  • Patent number: 8420174
    Abstract: The present invention relates to a composition for coating metallic surfaces, comprising a binder component; a corrosion inhibitor polymer based on an ethylenically monocarboxylic and dicarboxylic acid and, if appropriate, further ethylenical monomers, a solvent component, and, if appropriate, crosslinkable components, and also pigment/filler components.
