Abstract

See full text

The present invention relates to a method for manufacturing coated can lids from aluminum strip, and is based on the finding that flexible, easily formable coatings having high abrasion resistance result from the use of water-based lacquers containing a copolymer or a copolymer mixture of at least one aliphatic, acyclic alkene with at least one α,β-unsaturated carboxylic acid in water-dispersed form, and a curing system. In a preferred embodiment of the method, the application of a primer coating can be dispensed with entirely when water-soluble compounds of the elements Zr and/or Ti in the lacquer are used as the curing system.
