Title (EN) MULTILAYER POLYESTER FILM FOR OPTICAL USE
(FR) FILM POLYESTER MULTICOUCHE POUR USAGE OPTIQUE
(JA) 光学用積層ポリエステルフィルム
Abstract: front page image
(EN)Disclosed is a multilayer polyester film for optical use, which has excellent adhesion among a light diffusion layer, a prism layer and a hard coat layer without deteriorating transparency. In addition, the multilayer polyester film has excellent antistatic properties. Specifically disclosed is a biaxially oriented polyester film for optical use, which is characterized in that a coating layer containing a cationic polymer is arranged on one side of a polyester film and a layer obtained by applying a coating agent containing a polyurethane including a diol component having a polycarbonate structure and a heat crosslinking agent is arranged on the other side of the polyester film.
(FR)La présente invention concerne un film polyester multicouche pour usage optique, présentant une excellente adhésion entre une couche de diffusion de lumière, une couche prismatique, et une couche de revêtement dur, sans détérioration de la transparence. De plus, le film polyester multicouche présente d'excellentes propriétés antistatiques. Plus spécifiquement, l'invention concerne un film polyester orienté biaxialement pour usage optique, caractérisé en ce qu'une couche de revêtement contenant un polymère cationique est agencée sur un côté du film polyester, et en ce qu'une couche obtenue par application d'un agent de revêtement contenant du polyuréthanne comprenant un composant de diol à structure de polycarbonate et d'un agent de réticulation à chaud est agencée sur l'autre côté du film polyester.
(JA) 光拡散層、プリズム層、ハードコート層との接着性が良好で、透明性を損なうことなく、しかも帯電防止性能に優れた光学用積層ポリエステルフィルムを提供する。  ポリエステルフィルムの一方の面にカチオンポリマーを含む塗布層を有し、ポリカーボネート構造のジオール成分を有するポリウレタンと熱架橋剤とを含有する塗布剤を塗布して得られた層をもう一方の面に有することを特徴とする光学用二軸配向ポリエステルフィルム。
