MULTILAYER PRESSURE SENSITIVE ADHESIVE FILMS WITH PRESSURE SENSITIVE ADHESIVES COMPRISING (METH) ACRYLATE ESTERS OF 2 ALKYL ALKANOLS

摘要

1 12The present invention is directed to a multilayer pressure sensitive adhesive (PSA) film having a first pressure sensitive adhesive layer and at least one opposing layer characterized in that the first pressure sensitive adhesive layer comprises a pressure sensitive adhesive composition comprising (co)polymers of : a) (meth)acrylate ester of 2 alkyl alkanols wherein the molar carbon number average of said 2 alkyl alkanols is 12 to 32; and optionally b) (meth)acrylate esters of C alkanols; wherein the molar carbon number average of the alkanols of the a) and b) (meth)acrylic acid esters is 12 to 32; wherein the at least one opposing layer comprises at least one filler material selected from the group of filler particles wherein the filler particles are expanded perlite. The invention is also directed to a method for the manufacturing of such a multilayer PSA film and its use.
