Abstract
A coating composition comprises the following components dissolved in an organic solvent therefor: PA0 (I) an addition copolymer derived from ethylenically unsaturated monomers and containing (a) from 0.8 to 8.0% by weight, based on the total weight of the polymer, of free carboxyl groups, and, optionally, (b) tertiary amino groups; PA0 (II) one or more polyepoxide compounds present in an amount to provide from 0.2 to 2 epoxy groups for each carboxy group in the addition copolymer; PA0 (III) an aluminum, titanium or zirconium alkoxide or complex thereof with a chelating agent therefor, present in an amount such that the amount of metal is from 0.05 to 2.0% by weight, based on the weight of the addition copolymer; and PA0 (IV) optionally, a tertiary amino compound; provided that component (IV) is present when the addition copolymer (I) does not contain tertiary amino groups and that the total amount of tertiary amino groups present in the composition provides from 0.1 to 2% by weight, based on the weight of the addition copolymer (I), of nitrogen.
