Claim:
1. A liquid coating composition comprising a) from 10 to 40 wt %, based on the weight of components a) through e), of an acrylic based polymer comprising acrylate or methacrylate pendant groups prepared by reacting glycidyl acrylate and/or glycidyl methacrylate with a co-polymer prepared from a mixture of monomers comprising at least one acrylic and/or methacrylic acid monomer and one or more monomers of formula Ia and/or IIa, wherein R, R′ and R″ are independently selected from methyl and hydrogen; G is C n is 2 or 3, and Z is straight or branched chain C b) from 50 to 89 wt % of one or more reactive monomers having a boiling point at 1 atmosphere of greater than 100° C. wherein at least 50 mole % of the reactive monomers are selected from the group consisting of compounds of formula I and compounds comprising two or more reactive groups of formula II, wherein R, R′ and R″ are each individually selected from H, C Y is selected from H, C c) 0.1 to 10 wt % of a thermally activated or UV activated radical initiator, d) 0 to 10 wt % of a non-polar, inert wax or oil, and e) 0 to 5 wt % of a tertiary amine, wherein the coating composition has a viscosity of 50,000 cps or less at 25° C.
