ABSTRACT:
Ultraviolet-curable liquid coating compositions are disclosed in which improved adhesion to metal and plastic surfaces is obtained. This improvement is obtained by using, in admixture: (1) from 10% to about 60% of total resin solids of an organic solvent-soluble solution copolymer of monoethylenically unsaturated monomers including from 2.5% to 10% of tertiary amine monomer which is an aminoalkyl ester or amide of an alpha, beta-monoethylenic monocarboxylic acid in which the alkyl group contains 2-4 carbon atoms; and (2) from 40% to 90% of total resin solids of radiation-curable ethylenically unsaturated liquid. The coating composition includes photoinitiators and/or photosensitizers rendering the composition sensitive to ultraviolet light, and the components are present in solution in at least about 10% of inert volatile organic solvent.
