MULTILAYER PRESSURE-SENSITIVE ADHESIVE FILMS WITH A (METH)ACRYLIC-BASED ELASTOMERIC MATERIAL
摘要
<p>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 R 1 -OH, the alkyl (meth)acrylate ester being of Formula (I)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ CH 2 =C(R 2 )-(CO)-OR 1 €ƒ€ƒ€ƒ€ƒ€ƒ(I)
wherein
R 1 is an alkyl having 14 to 25 carbon atoms and the primary alcohol R 1 -OH has an iso number equal to at least 2 but no greater than 4,
R 2 is hydrogen or methyl; and
(b) a second monomer having an ethylenically unsaturated group. The invention is also directed to a method for the manufacturing of such a multilayer PSA film and its use.</p>
