Title (EN) WINDOW FILM
(FR) FILM DE FENÊTRE
(JA) ウィンドウフィルム
Abstract:
(EN) [Problem] To provide a window film with which haze is suppressed and the adhesiveness of a laminate in a high-temperature, high-pressure environment is improved. [Solution] Provided is a window film that includes a first substrate and a functional layer (A) that includes anionic metal oxide particles and a polyurethane resin having a hydrophilic group, and a polyvinyl alcohol resin, wherein the content of the polyvinyl alcohol resin in the functional layer (A) is 0.2-0.8 parts by mass relative to 1 part by mass of the polyurethane resin.
(FR) Le problème décrit par la présente invention est de fournir un film de fenêtre grâce auquel un trouble est supprimé et l'adhérence d'un stratifié dans un environnement à haute température et à haute pression est améliorée. La solution selon l'invention concerne un film de fenêtre qui comprend un premier substrat et une couche fonctionnelle (A) qui comprend des particules d'oxyde métallique anioniques et une résine de polyuréthane ayant un groupe hydrophile, et une résine d'alcool polyvinylique, la teneur de la résine d'alcool polyvinylique dans la couche fonctionnelle (A) étant de 0,2 à 0,8 partie en masse par rapport à 1 partie en masse de la résine de polyuréthane.
(JA) 【課題】ヘイズが抑えられ、高温高圧環境下での積層体の密着性が向上されたウィンドウフィルムを提供する。 【解決手段】第1の基材、ならびに親水基を有するポリウレタン樹脂、アニオン性金属酸化物粒子、ならびにポリビニルアルコール樹脂を含む機能層(A)を含み、機能層(A)におけるポリビニルアルコール樹脂の含有量が、ポリウレタン樹脂1質量部に対して0.2~0.8質量部である、ウィンドウフィルムである。
