ABSTRACT:
The invention provides a coating composition for coating aluminum which is based on vinyl ester copolymers and an organic solvent, the vinyl ester copolymer comprising
a) 20 to 90 parts by weight of a vinyl ester of saturated aliphatic monocarboxylic acids having 1 to 5 C atoms,
b) 0 to 70 parts by weight of a vinyl ester of saturated aliphatic monocarboxylic acids which have 9 to 10 C atoms and a quaternary C atom in the .alpha.-position relative to the carboxyl group,
c) 0.05 to 10 parts by weight of one or more ethylenically unsaturated mono- or dicarboxylic acids having 3 to 10 C atoms or anhydrides thereof and
d) 0 to 50 parts by weight of one or more ethylenically unsaturated monomers, the homopolymers of which have a glass transition temperature above 30.degree. C.
The coating composition is free of chlorine-containing polymers and also avoids the necessity for using a chlorine-containing primer.
