Abstract

L'invention concerne une composition adhésive sensible à la pression utilisée pour les filtres optiques de panneaux d'affichage, qui est caractérisée en ce qu'elle contient un copolymère d'ester d'acide (méth)acrylique (A) ayant un groupe fonctionnel réticulable dans une molécule, un agent de réticulation (B) et un agent absorbant le rayonnement proche infrarouge (C) composé d'un oxyde de tungstène composite. Cette composition adhésive sensible à la pression est en outre caractérisée en ce qu'elle possède un module de conservation (G') à 80 °C de 1 × 104 à 1 × 106 Pa et une température de transition vitreuse (Tg) pas inférieure à -30 °C après réticulation. Cette composition adhésive sensible à la pression pour affichages présente de bonnes caractéristiques optiques, mais aussi une durabilité et une résistance aux intempéries excellentes. Par conséquent, cette composition adhésive sensible à la pression permet d'obtenir un filtre optique à faible coût en simplifiant une structure en couches d'un filtre optique pour écrans plasma ou panneaux d'affichage à cristaux liquides dans laquelle plusieurs films fonctionnels sont stratifiés.
