| abstract |
The invention relates to a coating agent composition for coating aluminium, based on vinyl ester copolymers and an organic solvent, where the vinyl ester copolymer contains A) from 20 to 90 parts by weight of a vinyl ester of saturated, aliphatic monocarboxylic acids having 1 to 5 carbon atoms, B) from 0 to 70 parts by weight of a vinyl ester of saturated, aliphatic monocarboxylic acids having 9 to 10 carbon atoms which contain a quaternary carbon atom in the alpha -position to the carboxyl group, C) from 0.05 to 10 parts by weight of one or more ethylenically unsaturated mono- or dicarboxylic acids having 3 to 10 carbon atoms, or anhydrides thereof, D) from 0 to 50 parts by weight of one or more ethylenically unsaturated monomers whose homopolymers have a glass transition temperature of above 30 DEG C. |
