Abstract
(DE) Die vorliegende Anmeldung betrifft eine opake, biaxial orientierte Polyesterfolie mit mindestens einer Basisschicht, deren kennzeichnende Merkmale darin besteht, dass zumindest diese Basisschicht ein Cycloolefincopolymeres (COC) in einer Konzentration von 2 bis 60 Gew.-%, bezogen auf die Basisschicht enthält, wobei die Glasübergangstemperatur des Cycloolefincopolymeren (COC) im Bereich von 70 bis 270 °C liegt und dass zumindest eine Oberfläche haftvermittelt ist.
(EN) The invention relates to an opaque, biaxially oriented polyester film comprising at least one base layer, characterised in that at least this base layer contains a cyclic olefin copolymer (COC) in a concentration of 2 to 60 wt. % in relation to the base layer, the glass transition temperature of said cyclic olefin copolymer (COC) being 70 to 270 °C; and in that at least one surface is provided with a coupling agent.
(FR) La présente invention concerne une feuille polyester opaque à orientation biaxiale comprenant au moins une couche de base se caractérisant en ce qu"au moins cette couche de base contient un polymère cyclooléfinique (COC) avec une concentration allant de 2 à 60 % en poids de la couche de base, la température de transition vitreuse du polymère cyclooléfinique (COC) se situant dans la zone allant de 70 à 270 °C, et en ce qu"au moins une surface est rendue adhérente.
