Abstract:
(EN) The purpose of the invention is to provide a laminated optical film capable of achieving both high voidage (porosity) and excellent scratch resistance. In this laminated optical film, a void layer is formed on a resin film, and a cover layer is directly formed on the void layer. The void layer has a water contact angle of 90° or greater and a voidage of 30 vol% or higher.
(FR) L'objectif de l'invention consiste à fournir un film optique stratifié pouvant obtenir à la fois un taux de vide (porosité) élevé et une excellente résistance aux rayures. Dans ce film optique stratifié, une couche de vide est formée sur un film de résine, et une couche de protection est formée directement sur la couche de vide. La couche de vide a un angle de contact avec l'eau de 90° ou plus et un taux de vide de 30 % en volume ou plus.
(JA) 本発明は、高い空隙率(空孔率)および優れた耐擦傷性を両立可能な積層光学フィルムの提供を目的とする。 本発明の積層光学フィルムは、 樹脂フィルム上に空隙層が形成され、 さらに、前記空隙層上にカバー層が直接形成され、 前記空隙層は、水の接触角が90°以上であり、かつ、空隙率が30体積%以上である。
