Title (EN) LAMINATED POLYESTER FILM AND MANUFACTURING METHOD THEREFOR
(FR) FILM DE POLYESTER STRATIFIÉ ET SON PROCÉDÉ DE FABRICATION
(KO) 적층 폴리에스테르 필름 및 이의 제조방법
Abstract: front page image
(EN)The present invention relates to a laminated polyester film and a manufacturing method therefor. The polyester film of the present invention is characterised by comprising: a first layer having a first polyester resin manufactured using a first catalyst; and a second layer having a second polyester resin manufactured using a second catalyst that is different from the first catalyst, wherein the first and the second layer are laminated. The polyester film according to the present invention has features of improved luminance and low oligomer elution, and can therefore be advantageously used as a substrate for ITO, a silver nanowire, a metal mesh, and a prism for an LCD backlight unit.
(FR)La présente invention se rapporte à un film de polyester stratifié et à son procédé de fabrication. Le film de polyester de la présente invention est caractérisé par le fait qu'il comprend : une première couche ayant une première résine de polyester fabriquée à l'aide d'un premier catalyseur ; et une seconde couche ayant une seconde résine de polyester fabriquée à l'aide d'un second catalyseur qui est différent du premier catalyseur, la première et la seconde couche étant stratifiées. Le film de polyester selon la présente invention présente les caractéristiques d'une meilleure luminance et d'une faible élution d'oligomère et peut, par conséquent, être avantageusement utilisé en tant que substrat de l'oxyde d'indium et d'étain (ITO pour Indium Tin Oxide), nanofil d'argent, maille métallique et prisme pour une unité de rétroéclairage d'affichage à cristaux liquides (LCD pour Liquid Crystal Display).
(KO)본 발명은 적층 폴리에스테르 필름 및 이의 제조방법에 관한 것으로서, 본 발명의 폴리에스테르 필름은 제 1 촉매로 제조된 제 1 폴리에스테르 수지를 포함하는 제 1 층; 제 1 촉매와 다른 제 2 촉매로 제조된 제 2 폴리에스테르 수지를 포함하는 제 2 층을 적층된 형태로 포함하는 것을 특징으로 하며, 이러한 본 발명에 따른 폴리에스테르 필름은 향상된 휘도와 낮은 올리고머 용출 특성을 가지므로 ITO용 기재, 은 나노와이어용 기재, 금속 메쉬용 기재, LCD 백라이트 유닛용 프리즘의 기재로서 유용하게 사용될 수 있다.
