Abstract:
(EN) The present invention provides: a polarizing plate protective film having a polymer B1 layer containing a polymer B1 including repeating units (a) having a solubility parameter δt of 13.5 to less than 20.0 adjacent to at least one surface of a cellulose ester layer, wherein the polymer B1 layer is obtained by applying, on a surface of the cellulose ester layer, a composition containing the polymer B1 and a solvent satisfying specific relational expressions [1] and [2], and the water vapor permeability of the polarizing plate protective film under conditions of a temperature of 85°C and a relative humidity of 85% is 100 g/m2 to 1600 g/m2; a method for manufacturing the same; and a polarizing plate and a liquid crystal display device.
(FR) La présente invention concerne : un film de protection de plaque polarisante ayant une couche de polymère B1 contenant un polymère B1 comprenant des unités de répétition (a) ayant un paramètre de solubilité δt de 13,5 à moins de 20,0 de manière adjacente à au moins une surface d'une couche d'ester de cellulose, la couche de polymère B1 étant obtenue en appliquant, sur une surface de la couche d'ester de cellulose, une composition contenant le polymère B1 et un solvant satisfaisant des expressions relationnelles spécifiques [1] et [2], et la perméabilité à la vapeur d'eau du film de protection de plaque polarisante dans des conditions d'une température de 85 °C et d'une humidité relative de 85 % est de 100 g/m2 à 1600 g/m2 ; son procédé de fabrication ; et une plaque polarisante et un dispositif d'affichage à cristaux liquides.
(JA) セルロースエステル層の少なくとも一方の表面に隣接する、溶解度パラメータδtが13.5以上20.0未満の繰り返し単位〔a〕を含むポリマーB1を含有するポリマーB1層を有する偏光板保護フィルムであって、ポリマーB1層が、セルロースエステル層の表面上に、ポリマーB1と、特定の関係式[1]及び[2]を満たす溶媒とを含有する組成物を適用してなり、かつ、85℃、相対湿度85%の条件下、6時間での透湿度が100g/m以上1600g/m以下である偏光板保護フィルムと、その製造方法、並びに、偏光板及び液晶表示装置。
