Abstract:
(EN) Disclosed is a method for producing an optically functional film without causing appearance defects. Specifically disclosed is a method for producing an optically functional film comprising a coating step wherein a resin solution is applied over a base film which is composed of a thermoplastic resin, and an immobilization step wherein a resin layer is formed by immobilizing the coated resin. This method is characterized by comprising, before the coating step, a drawing step wherein the base film is drawn while being heated.
(FR) La présente invention concerne un procédé de production d'un film à fonctions optiques évitant l'apparition de défauts d'aspect. Elle porte spécifiquement sur un procédé de production d'un film à fonctions optiques qui comprend une étape de revêtement, consistant à appliquer une solution de résine sur un film de base composé d'une résine thermoplastique, et une étape d'immobilisation, consistant à immobiliser la résine appliquée pour obtenir une couche de résine. Ce procédé se caractérise en ce qu'il comporte, préalablement à l'étape de revêtement, une étape d'étirement qui vise à étirer le film de base en le chauffant.
(JA)  外観不良を生じさせることなく光学機能フィルムを製造することを一の課題とする。  熱可塑性樹脂からなる基材フィルム上に樹脂溶液を塗工する塗工工程と、塗工された樹脂を固定化して樹脂層を形成する固定化工程とを備えた光学機能フィルムの製造方法において、前記塗工工程の前段に、基材フィルムを加熱した状態で延伸する延伸工程を備えたことを特徴とする。
