ABSTRACT:
Liquid, curable coating compositions are provided based on an addition polymer containing hydroxyl groups and a curing agent. The compositions have a high solids content and hence a low solvent emission upon application. The addition copolymer contains structural units derived from isobornyl (meth)acrylate and/or a mono-ethylenically unsaturated compound of decahydronaphthalene and/or tricyclo(5.2.1.0.sup.2,6 ) and has a Mn of 600-15000 and a hydroxyl number of 30-320. The curing agent may be (blocked) isocyanate or methylolated aminoplast resin.
The composition may be applied to vehicles as a top coat.
