Abstract
This invention is concerned with coating and/or impregnating compositions comprising (a) A copolymer of 5 to 50% by weight of dicyclopentenyl acrylate or methacrylate with 50 to 95% by weight of at least one other monoethylenically unsaturated comonomer. (b) An essentially non-volatile reactive comonomer consisting of dicyclopentenyl acrylate or methacrylate or a mixture thereof, or comprising a mixture of at least 50% by weight of one or both of these monomers with up to 50% by weight of at least one other reactive monomer, such as a (C.sub.10 -C.sub.20)alkyl acrylate or methacrylate, a (C.sub.10 -C.sub.20)alkenyl acrylate or methacrylate, a di(C.sub.4 -C.sub.20)-alkyl fumarate, maleate, or itaconate, or a polyethylenically unsaturated monomer, such as a polyol polymethacrylate, e.g. glycol dimethacrylate, or the analogous diacrylate, or mixtures of two or more such monomers. (c) A polyvalent metal-containing complex or salt that catalyzes the oxidative curing of a) and b), such as cobalt naphthenate, and (d) A volatile oxime stabilizer. Such compositions are characterized by the fact that they can have exceptionally high solids content and rapid cure by air-drying to exceptional properties of hardness and resistance to solvents even without baking.
