Title (EN) STRETCHED MULTILAYER SYNTHETIC RESIN FILM
(FR) FILM DE RÉSINE SYNTHÉTIQUE MULTICOUCHE ÉTIRÉ
(JA) 合成樹脂積層延伸フィルム
Abstract:
(EN) The present invention relates to a stretched multilayer synthetic resin film which is suitable for use as a retardation film and the like. A stretched multilayer synthetic resin film according to the present invention comprises layers (A) that contain a resin (A) and a layer (B) that contains a resin (B); and the layers (A) are laminated on both surfaces of the layer (B). This stretched multilayer synthetic resin film is characterized in that: the resin (A) is a vinyl copolymer resin which contains a (meth)acrylic acid ester constituent unit (a) and an aliphatic vinyl constituent unit (b) having a cyclohexyl skeleton at a predetermined quantitative ratio; and the resin (B) is a vinyl copolymer resin which contains a styrene constituent unit (c) at a predetermined quantitative ratio. This film is also characterized by having an in-plane retardation Re within the range of from 0.0 nm to 30.0 nm and a retardation in the thickness direction Rth within the range of from -300 nm to -30 nm.
(FR) La présente invention concerne un film de résine synthétique multicouche étiré qui est approprié pour être utilisé en tant que film de retard et similaire. Un film de résine synthétique multicouche étiré selon la présente invention comprend des couches (A) qui contiennent une résine (A) et une couche (B) qui contient une résine (B) ; et les couches (A) sont stratifiées sur les deux surfaces de la couche (B). Ce film de résine synthétique multicouche étiré est caractérisé en ce que : la résine (A) est une résine de copolymère de vinyle qui contient une unité constitutive d'ester d'acide (méth) acrylique (a) et une unité constitutive de vinyle aliphatique (b) ayant un squelette cyclohexyle à un rapport quantitatif prédéterminé ; et la résine (B) est une résine de copolymère de vinyle qui contient une unité constitutive de styrène (c) à un rapport quantitatif prédéterminé. Ce film est également caractérisé en ce qu'il a un retard dans le plan Re dans la plage allant de 0,0 nm à 30,0 nm et un retard dans la direction d'épaisseur Rth dans la plage allant de 300 nm à -30 nm.
(JA) 本発明は、位相差フィルム等に好適に使用される合成樹脂積層延伸フィルムに関する。本発明の合成樹脂積層延伸フィルムは、樹脂(A)を含む層(A)および樹脂(B)を含む層(B)を有し、層(B)の両面に層(A)が積層され、前記樹脂(A)は、(メタ)アクリル酸エステル構成単位(a)と、シクロヘキシル骨格を有する脂肪族ビニル構成単位(b)とを所定の量比で含むビニル共重合樹脂であり、前記樹脂(B)は、スチレン構成単位(c)を所定の量比で含むビニル共重合樹脂であり、前記フィルムの面内位相差Reが0.0~30.0nmの範囲であり、かつ厚み方向位相差Rthが-300nm~-30nmの範囲であることを特徴とする。
