Abstract
Coated articles having improved chemical resistance comprising an article formed from a moldable polymer coated on at least one surface with a coating composition comprising at least one vinyl ether oligomer compound, and at least one photoinitiator are disclosed. Coatings which also contain at least one acrylate compound and/or at least one epoxy compound are also disclosed. The articles are preferably made from polyesters. Methods for coating such articles are also disclosed.
Claims27
A coated article comprising a moldable polyester polymer coated on at least a portion of at least one surface with a coating comprising at least one vinyl ether compound selected from the compounds of the formula:
- (R′CH═CR″—OZ)n—A
- where R′ and R″ may be the same or different and are independently selected from H or an alkyl group having 1 to 10 carbon atoms;
- A is a moiety derived from urethanes, phenols, polyesters, polyethers, polycarbonates, or polysiloxanes and has a molecular weight of about 400 to 10,000;
- Z is a moiety derived from a saturated aliphatic or cycloaliphatic hydrocarbon or a polyalkylene ether and has a molecular weight of about 28 to about 250;
- n is an integer of 2 or more;
- and at least one photoinitiator.
