More Information
Summary:Pressure sensitive adhesive articles include a substrate with a first major surface and a second major surface, and a pressure sensitive adhesive layer disposed on at least a portion of the first major surface of the substrate. The pressure sensitive adhesive layer is an E-beam cured composition of a (meth)acrylate-based polymer that is free from acidic-functional or amide-functional groups and at least one tackifier that is a hydrogenated hydrocarbon resin. The pressure sensitive adhesive layer has a static shear of at least 600 minutes to protein leather. L'invention concerne des articles adhésifs sensibles à la pression comprenant un substrat présentant une première surface principale et une seconde surface principale et une couche adhésive sensible à la pression disposée sur au moins une partie de la première surface principale du substrat. La couche adhésive sensible à la pression est une composition durcie par faisceau électronique d'un polymère à base de (méth)acrylate qui est exempt de groupes à fonctionnalité acide ou amide et d'au moins un agent poisseux qui est une résine hydrocarbonée hydrogénée. La couche adhésive sensible à la pression présente un cisaillement statique d'au moins 600 minutes sur un cuir protéique.
