Abstract: Described herein is a pressure sensitive adhesive composite composition. The composition comprises: a plurality of polymeric microspheres dispersed within a (meth)acrylate-based matrix, wherein the polymeric microspheres are derived from 20-100 wt % of isobornyl (meth)acrylate; and the (meth)acrylate-based matrix comprises an at least partially polymerized reaction product comprising a C4 to C20 (meth)acrylate ester monomer. In some embodiment, these composite pressure sensitive adhesives show good peel adhesion to low surface energy substrates. In some embodiment, these composite pressure sensitive adhesives are optically clear.

Abstract: A principal film comprising a first polymeric component wherein the principal film has: (1) first and second major faces; (2) a land portion wherein the principal film is capable of thermally-induced self-forming; and (3) one or more modification zones, each comprising a central portion and a rim portion surrounding the central portion and being surrounded by land portion, wherein the average thickness of each rim portion is greater than the average thickness of the land portion surrounding the modification zone, the average thickness of each central portion is less than the average thickness of the land portion surrounding the modification zone and is greater than zero. Also methods for making such films and articles comprising such films.
