(Meth)acrylate pressure-sensitive adhesives,curable adhesive compositions that can be used to prepare the(meth)acrylate pressure-sensitive adhesives,and methods of making the(meth)acrylate pressure-sensitive adhesives are provided.More particularly,the(meth)acrylate pressure-sensitive adhesives contain(a)a meth(acrylate copolymer having a weight average molecular weight greater than 500,000grams/mole(Daltons)and(b)a(meth)acrylate tackifier that has a weight average molecular weight greater than20,000grams/mole(Daltons)but no greater than200,000grams/mole(Daltons).The pressure-sensitive adhesives advantageously are prepared by ultraviolet(UV)curing a curable adhesive composition that contains minimal or no organic solvents.
