Abstract
Disclosed herein is a primerless removable pressure sensitive adhesive construction comprising an unprimed facestock, a first adhesive layer in contact with the facestock, a second removable pressure sensitive adhesive layer in contact with the first adhesive layer, and a release surface in contact with the second adhesive layer. Advantageously, constructions of this design exhibit improved layflatness in comparison to conventional emulsion primed removable pressure sensitive adhesive constructions.
