Abstract: Adhesive articles with multi-layer adhesive constructions include a substrate and a multi-layered adhesive. The multi-layered adhesive includes a layer of a first adhesive in contact with the surface of the substrate, and a layer of siloxane-based pressure sensitive adhesive in contact with the first adhesive. The siloxane-based pressure sensitive adhesive includes a siloxane-(meth)acrylate co-polymer. The thickness of the siloxane-based pressure sensitive adhesive layer is less than the thickness of the first adhesive layer.
