Abstract: front page image
(EN)The present invention relates to an adhesive sheet, a manufacturing method thereof, an optical filter and a plasma display panel. The present invention provides an adhesive sheet having an excellent base adhesion property through a hydroxyl group applied to a base film and an isocyanate-based compound contained in an adhesive layer through a corona processing. Accordingly, the present invention provides an adhesive sheet having an excellent base adhesion property and improved high temperature stability by using a carboxyl group-containing acryl-based copolymer having a high glass transition temperature. Further, the adhesive sheet of the present invention contains a siloxane-based compound if needed, thus preventing an initial peeling force from being increased. Accordingly, the present invention provides an adhesive sheet with an excellent base adhesion property, high temperature stability, adhesive property and reworkability to glass, and provides a manufacturing method thereof, an optical filter containing the same and a plasma display panel.
(FR)La présente invention concerne une feuille adhésive, un procédé de fabrication de celle-ci, un filtre optique et un panneau afficheur plasma. La présente invention concerne une feuille adhésive possédant une propriété d'adhérence de base excellente par l'intermédiaire d'un groupe hydroxyle appliqué à un film de base et d'un composé à base d'isocyanate contenu dans une couche adhésive par un traitement corona. Par conséquent, la présente invention concerne une feuille adhésive possédant une excellente propriété d'adhérence de base et une stabilité à haute température améliorée par l'utilisation d'un copolymère à base d'acryle contenant un groupe carboxyle possédant une température de transition vitreuse élevée. Par ailleurs, la feuille adhésive de la présente invention contient, le cas échéant, un composé à base de siloxane, empêchant ainsi l'accroissement d'une force de pelage initiale. Par conséquent, la présente invention concerne une feuille adhésive avec une propriété d'adhérence de base excellente, une stabilité à température élevée, une propriété adhésive et une possibilité de la retravailler sur le verre excellentes, ainsi qu'un procédé de fabrication de cette feuille, un filtre optique contenant cette feuille et un panneau afficheur plasma.
(KO)본 발명은 점착 시트, 그 제조 방법, 광학 필터 및 플라즈마 디스플레이 패널에 관한 것이다. 본 발명에서는 코로나 처리에 의해 기재 필름에 도입된 히드록시기와 점착제층에 포함되는 이소시아네이트계 화합물을 통하여, 우수한 기재 밀착성을 가지는 점착 시트를 제공할 수 있다. 이에 따라, 본 발명에서는 높은 유리전이온도를 갖는 카복실기 함유 아크릴계 공중합체를 사용하여, 점착 시트의 고온 안정성을 개선하면서도, 우수한 기재 밀착성을 가지는 점착 시트를 제공할 수 있다. 또한, 본 발명의 점착 시트는, 경우에 따라서 실록산계 화합물을 포함하여, 초기 박리력의 상승이 방지될 수 있다. 이에 따라 본 발명에서는 우수한 기재 밀착성, 고온 안정성, 유리에 대한 접착성 및 재작업성을 갖는 점착 시트, 그 제조 방법, 상기를 포함하는 광학 필터 및 플라즈마 디스플레이 패널을 제공할 수 있다.
