Crosslinked (meth)acrylate-based pressure sensitive adhesives are capable of attachment to mammalian skin for at least 10 days. The crosslinked adhesive composition includes a crosslinked (meth)acrylate-based copolymer free from polar groups, and a hydrogenated hydrocarbon tackifier resin. The crosslinked adhesive composition is prepared by photocrosslinking a hot melt processable blend of a (meth)acrylate copolymer and a hydrogenated hydrocarbon tackifier resin. The (meth)acrylate copolymer is the reaction product of an alkyl (meth)acrylate monomer with alkyl groups of 4-22 carbon atoms and are free of polar groups, and a copolymerizable photocrosslinker.
