Abstract:
The present invention is directed to a multilayer pressure sensitive adhesive (PSA) film, having a first pressure sensitive adhesive layer and at least an opposing layer, wherein the first pressure sensitive adhesive layer comprises a pressure-sensitive adhesive composition with a (meth)acrylic-based elastomeric material comprising a reaction product of polymerizable material comprising: (a) a first monomer which is an alkyl (meth)acrylate ester of a primary alcohol R1—OH, the alkyl (meth)acrylate ester being of Formula (I) CH2═C(R2)—(CO)—OR1 (I) wherein R1 is an alkyl having 14 to 25 carbon atoms and the primary alcohol R1—OH has an iso index equal to at least 2 but no greater than 4; R2 is hydrogen or methyl; and (b) a second monomer having an ethylenically unsaturated group; wherein the at least one opposing layer comprises at least one filler material. The invention is also directed to a method for the manufacturing of such a multilayer PSA film and its use.
