ABSTRACT:
An air oxidizable coating composition is disclosed comprising an ungelled urethane modified alkyd resin containing pendant polymerizable unsaturated groups attached to the alkyd through urethane linkages. The ungelled urethane modified alkyd is the reaction product of components comprising a hydroxyl containing, air oxidizable alkyd resin having an oil length of between about 20 percent and about 70 percent and an isocyanate-functional ethylenically unsaturated compound. Also disclosed are a process for coating the substrate with the coating composition and certain ungelled urethane modified alkyd resins.
