Abstract
Coating composition containing at least one free radical polymerizable ethylenically unsaturated monomer, and a chain extended polyurethane polymer having terminally ethylenically unsaturated groups and preferably polymeric urea linkages, said polymer having a molecular weight of between about 2,000 and 20,000. The polymerizable monomer is at least a partial solvent for the polymer. The coating compositions may be cured by free radical reactions to yield tough, mar-resistant coatings.
