Abstract
Acrylic copolymer compositions which contain a tackifying hydrocarbon resin and a polyfunctional crosslinking monomer and the use of such composition in pressure-sensitive adhesives are described. The tackifying hydrocarbon resin is dissolved, as is the polyfunctional monomer, in a solution of alkyl(meth)acrylate and (meth) acrylic acid monomers and is present during the polymerization of the monomers to form a tackified acrylic copolymer.
