Title (EN) POLYESTER FILM FOR OPTICAL FUNCTIONAL SHEET
(FR) FILM DE POLYESTER POUR FEUILLE FONCTIONNELLE OPTIQUE
(JA) 光学機能シート用ポリエステルフィルム
Abstract:
(EN) Provided is a polyester film suitable for use as optical films, the polyester film having a high degree of optical properties and being capable of retaining the flatness after formation of an optical functional layer such as a lens layer thereon. The polyester film, which is for optical functional sheets, is used in applications where an optical resin layer is formed from an actinic-ray-curable composition on a surface of the polyester film. The polyester film has a machine-direction shrinkage stress at 95ºC of higher than 0 MPa and a machine-direction shrinkage stress at 100ºC in the range of 0.3-1.5 MPa.
(FR) La présente invention concerne un film de polyester pouvant être utilisé comme film optique, le film de polyester présentant un degré élevé de propriétés optiques et pouvant conserver sa planéité après formation sur lui d'une couche fonctionnelle optique telle qu'une couche formant lentille. Le film de polyester, qui est destiné à des feuilles fonctionnelles optiques, est utilisé dans des applications où une couche de résine optique est formée à partir d'une composition durcissable par rayonnement actinique sur une surface du film de polyester. Le film de polyester présente une contrainte due au retrait dans le sens machine à 95 ºC supérieure à 0 MPa et contrainte due au retrait dans le sens machine à 100 ºC dans la plage de 0,3 à 1,5 MPa.
(JA)  高度な光学特性を持ち、かつ、レンズ層等の光学機能層を賦形した後のポリエステルフィルムの平面性を保つことができる、光学フィルム用として好適に利用することのできるポリエステルフィルムを提供する。 ポリエステルフィルムの表面に活性エネルギー線硬化性組成物により光学樹脂層を形成する用途に使用される光学機能シート用ポリエステルフィルムであって、95℃におけるフィルム長手方向の収縮応力が0MPaより大きく、かつ、100℃におけるフィルム長手方向の収縮応力が0.3~1.5MPaの範囲である光学機能シート用ポリエステルフィルム。
