Abstract

The present disclosure is directed to a multilayer pressure sensitive adhesive (PSA) assembly, comprising at least one pressure sensitive adhesive layer and a polymeric foam layer, wherein the pressure sensitive adhesive layer comprises a pressure-sensitive adhesive composition comprising a reaction product of a polymerizable material comprising: a) 2-propylheptyl acrylate as a first monomer; and optionally b) a second monomer having an ethylenically unsaturated group. The present disclosure is also directed to a method of manufacturing such a multilayer PSA assembly.
