Title
(EN) METHOD FOR PRODUCING LONG OPTICAL FILM CONTAINING POLYIMIDE RESIN
(FR) PROCÉDÉ DE FABRICATION DE FILM OPTIQUE ALLONGÉ CONTENANT UNE RÉSINE À BASE DE POLYIMIDE
(JA) ポリイミド系樹脂を含む長尺状光学フィルムの製造方法
Abstract
(EN) The present invention relates to a method for producing a long optical film, the method comprising a step for preparing a varnish by dissolving a polyimide resin in a solvent, wherein the polyimide resin contains aliphatic diamine-derived structural units, and the moisture absorption speed of the solvent per unit surface area is 25 mass%/h∙m2 or less as determined by the Karl Fischer method.
(FR) L'invention concerne un procédé de fabrication de film optique allongé qui inclut une étape au cours de laquelle une résine à base de polyimide est dissoute dans un solvant et un vernis est préparé. Ladite résine à base de polyimide contient une unité structurale dérivée d'un diamine aliphatique. La vitesse d'absorption d'humidité dudit solvant pour une surface unitaire mesurée selon le procédé de Karl Fischer, est inférieure ou égale à 25% en masse /h・m.
(JA) 本発明は、ポリイミド系樹脂を溶媒に溶解してワニスを調製する工程を含む長尺状光学フィルムの製造方法であって、前記ポリイミド系樹脂は脂肪族系ジアミン由来の構成単位を含み、前記溶媒の、カール・フィッシャー法により測定される単位面積当たりの吸湿速度は25質量%/h・m以下である、長尺状光学フィルムの製造方法に関する。
