Abstract:
(EN) Provided are an adhesive composition, an adhesive layer, and an optical film provided with the adhesive layer, which are free of problems regarding durability and defective appearance caused by an antistatic agent (conductive agent), and which have superior antistatic properties so as to be used for applications such as in an image display panel. Also provided are an image display panel attached, without an interposed conductive layer, with the optical film provided with an adhesive layer, to the surface of the image display panel in contact with the adhesive layer, and a liquid crystal display having the image display panel. This adhesive composition for an image display panel is characterized by containing an ionic liquid and a (meth)acrylic polymer containing, as a monomer unit, at least one monomer selected from the group consisting of carboxyl group-containing monomers, amino group-containing monomers, and amide group-containing monomers, wherein the amount of the least one monomer is equal to or more than 1.5 wt% of the total amount of the monomers.
(FR) L'invention concerne une composition adhésive, une couche adhésive, et un film optique pourvu de ladite couche adhésive, qui sont exempts de problèmes en termes de durabilité et d'aspect défectueux provoqués par un agent antistatique (agent conducteur), et qui possèdent des propriétés antistatiques supérieures de façon à pouvoir être utilisés dans des applications telles que dans un écran d'affichage d'images. L'invention concerne également un écran d'affichage d'images fixé, sans couche conductrice interposée, avec le film optique pourvu d'une couche adhésive, à la surface de l'écran d'affichage d'images en contact avec la couche adhésive, et un affichage à cristaux liquides comportant ledit écran d'affichage d'images. La composition adhésive pour écran d'affichage d'images selon l'invention est caractérisée en ce qu'elle contient un liquide ionique et un polymère (méth)acrylique contenant, à titre de motif monomère, au moins un monomère choisi dans le groupe constitué par les monomères contenant un groupe carboxyle, les monomères contenant un groupe amino, et les monomères contenant un groupe amide, la quantité dudit au moins monomère étant égale ou supérieure à 1,5 % en poids de la quantité totale des monomères.
(JA) 帯電防止剤(導電剤)による外観不良や耐久性の問題がなく、帯電防止性にも優れた画像表示パネル用途に使用できる粘着剤組成物、粘着剤層、及び、粘着剤層付光学フィルムを提供すること。また、前記粘着剤層付光学フィルムを粘着剤層と接する画像表示パネルの表面に、導電層を介することなく貼付されている画像表示パネル、前記画像表示パネルを有する液晶表示装置を提供すること。本発明の画像表示パネル用粘着剤組成物は、モノマー単位として、カルボキシル基含有モノマー、アミノ基含有モノマー、及び、アミド基含有モノマーからなる群より選択される少なくとも1種のモノマーを全モノマー中、1.5重量%以上含有する(メタ)アクリル系ポリマー、及び、イオン液体を含有することを特徴とする。
