Title (EN) MULTILAYER OPTICAL FILM HAVING HIGH HEAT RESISTANCE, AND METHOD FOR MANUFACTURING SAME
(FR) FILM OPTIQUE MULTICOUCHES AYANT UNE RÉSISTANCE À LA CHALEUR ÉLEVÉE ET PROCÉDÉ DE FABRICATION
(KO) 고내열성 다층 광학필름 및 그의 제조방법
Abstract: front page image
(EN)The present invention relates to a multilayer optical film having a structure in which a first resin layer and a second resin layer are alternately laminated, wherein the first resin layer comprises a crystalline naphthalene dicarboxylic-acid polyester and the second resin layer comprises polyethylene terephthalate glycol (PETG). Further, the present invention relates to a method for manufacturing a multilayer optical film, comprising the steps of: (a) alternately laminating a first resin comprising a crystalline naphthalene dicarboxylic-acid polyester and a second resin comprising PETG having undergone melt extrusion; and (b) stretching the laminated sheet from step (a) and then thermosetting the latter.
(FR)La présente invention concerne un film optique multicouches présentant une structure dans laquelle une première couche de résine et une seconde couche de résine sont stratifiées de manière alternée, la première couche de résine comprenant un polyester d'acide dicarboxylique de naphtalène cristallin et la seconde couche de résine comprenant un poly (téréphtalate d'éthylèneglycol) (PETG). En outre, la présente invention concerne un procédé de fabrication d'un film optique multicouches, comprenant les étapes suivantes : (a) la stratification en alternance d'une première résine comprenant un polyester d'acide dicarboxylique de naphtalène cristallin et d'une seconde résine comprenant un PETG ayant subi une extrusion par fusion ; et (b) l'étirement de la feuille stratifiée à partir de l'étape (a) puis le thermodurcissement de ce dernier.
(KO)본 발명은 다층 광학필름으로서 결정성 나프탈렌 디카복실산 폴리에스테르를 포함하는 제 1수지층; 및 폴리에틸렌테레프탈레이트글리콜(PETG)을 포함하는 제 2수지층이 교대로 적층된 구조를 가지는 다층 광학필름을 제공한다. 또한 (a) 결정성 나프탈렌 디카복실산 폴리에스테르를 포함하는 제 1수지 및 폴리에틸렌테레프탈레이트글리콜(PETG)을 포함하는 제 2수지를 각각 용융 압출한 뒤 교대로 적층하는 단계; 및 (b) 상기 단계 (a)에서 적층된 시트를 연신한 뒤 열고정하는 단계를 포함하는 다층 광학필름의 제조방법을 제공한다.
