Title (EN) MULTILAYER PRESSURE-SENSITIVE ADHESIVE FILMS WITH A (METH)ACRYLIC-BASED ELASTOMERIC MATERIAL
(FR) FILMS ADHÉSIFS SENSIBLES À LA PRESSION MULTICOUCHES AVEC UN MATÉRIAU ÉLASTOMÈRE À BASE (MÉTH)ACRYLIQUE
Abstract: front page image
(EN)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.
(FR)La présente invention concerne un film adhésif sensible à la pression multicouche (PSA), ayant une première couche adhésive sensible à la pression et au moins une couche opposée, dans lequel la première couche adhésive sensible à la pression comprend une composition adhésive sensible à la pression avec un matériau élastomère à base (méth)acrylique comprenant un produit de la réaction d'un matériau polymérisable comprenant : (a) un premier monomère qui est un ester de (méth)acrylate d'alkyle d'un alcool primaire R1-OH, l'ester de (méth)acrylate d'alkyle étant de Formule (I) CH2=C(R2)-(CO)-OR1 (I) dans laquelle R1 est un alkyle ayant 14 à 25 atomes de carbone et l'alcool primaire R1-OH a un indice iso égal à au moins 2 mais non supérieur à 4 ; R2 est hydrogène ou méthyle ; et (b) un second monomère ayant un groupement éthyléniquement insaturé ; dans lequel l'au moins une couche opposée comprend au moins un matériau de charge. L'invention concerne aussi un procédé pour la fabrication d'un tel film PSA multicouche et son utilisation.
