欧洲专利检索Priority number：WO2015157019

Abstract：Adhesive coated articles are described comprising a substrate comprising a first major surface and a second opposing major surface and a pressure sensitive adhesive layer disposed on the first major surface of the substrate. In one embodiment, the pressure sensitive adhesive layer is cleanly removable from paper, reusable, and has a shear to orange peel dry wall with a 250 g weight of at least 500 minutes. The pressure sensitive adhesive layer is preferably a multilayer adhesive. In another embodiment, an adhesive coated article is described comprising a substrate comprising a first major surface and a second opposing major surface and a multilayer pressure sensitive adhesive layer disposed on the first major surface of the substrate. The multilayer pressure sensitive adhesive comprises a first adhesive layer disposed on the first major surface of the substrate, and a second pressure sensitive adhesive skin layer disposed upon the first layer. At least the second skin layer is an acrylic multilayer adhesive comprising no greater than 1 wt-% of polymerized units derived from acid functional monomers. In some favored embodiments, the first adhesive layer is conformable.
