Abstract
Adhesive articles include a substrate; and a hot melt processable pressure sensitive adhesive on the substrate. The hot melt processable pressure sensitive adhesive is a (meth)acrylate-based copolymer that is the reaction product of a reaction mixture that is free of acidic or basic monomers, and includes an alkyl (meth)acrylate, a hydroxyl-functional (meth)acrylate, and a photocrosslinker. The (meth)acrylate-based polymer is prepared in a thermoplastic package.
