    Abstract: The present disclosure generally relates to conformable adhesive articles that are capable of attaching or adhering to a substrate and that can be removed from the substrate without causing damage to the substrate. The present disclosure also generally relates to methods of making and using such adhesive articles. In some embodiments, the adhesive article includes (1) a releasable layer having a first major surface and a second major surface; the second major surfaces including a pressure sensitive adhesive capable of adhering the adhesive article to a surface; and (2) a compliant layer having a first major surface and a second major surface; the second major surface of the compliant layer adjacent to the first major surface of the releasable layer. In some embodiments, the releasable layer debonds from both the surface and the compliant layer when the adhesive article is stretch released at an angle of less than 35 degrees.

    Abstract: Adhesives suitable for use with low surface energy materials are described. The adhesive contain an acrylic copolymer, a high glass transition temperature tackifier and a low glass transition temperature tackifier. The acrylic copolymer is the reaction product of a first alkyl(meth)acrylate having at least 5 carbon atoms in the alkyl group, a second alkyl(meth)acrylate having 1 to 4 carbon atoms in the alkyl group, and a vinyl carboxylic acid. Both tackifiers have a Tg greater than the Tg of the acrylic copolymer. The high glass transition temperature tackifier has a Tg of at least 20° C. and the low glass transition temperature tackifier has a Tg of less than 0° C.
