Abstract:
(EN) Provided is a peelable multilayer film in which a translucent film and a base material film containing polyethylene terephthalate are laminated, wherein: the base material film and the translucent film are in direct contact with each other; the translucent film has a thickness of 0.1-10 μm; the translucent film contains a resin having a solubility parameter value of 19-21 (J/cm3)0.5; and the weight-average molecular weight of the polyethylene terephthalate is 80,000 or less. Also provided are a method for producing a polarizing plate using the peelable multilayer film, and a polarizing plate having the translucent film.
(FR) Cette invention concerne un film multicouche pelable dans lequel un film translucide et un film de matériau de base contenant du polythéréphtalate d'éthylène sont stratifiés, le film de matériau de base et le film translucide étant en contact direct l'un avec l'autre. Le film translucide a une épaisseur de 0,1 à 10 µm. Le film translucide contient une résine ayant une valeur de paramètre de solubilité de 19 à 21 (J/cm3)0,5, et la masse moléculaire moyenne en poids du polytéréphtalate d'éthylène est inférieure ou égale à 80000. L'invention concerne en outre un procédé de production d'une plaque de polarisation mettant en œuvre le film multicouche pelable, et une plaque de polarisation comprenant le film translucide.
(JA) ポリエチレンテレフタレートを含む基材フィルムと透光性フィルムとが積層された剥離性積層フィルムであって、基材フィルムと透光性フィルムとが直接接しており、透光性フィルムの厚みが0.1~10μmであり、透光性フィルムは溶解性パラメータ値が19~21(J/cm0.5である樹脂を含み、ポリエチレンテレフタレートの重量平均分子量は80,000以下である、剥離性積層フィルム、上記剥離性積層フィルムを用いた偏光板の製造方法、上記透光性フィルムを有する偏光板。
