Title (EN) ANTI-REFLECTION FILM
(FR) FILM ANTIREFLET
(JA) 反射防止フィルム
Abstract:
(EN) This anti-reflection film (X) has a laminated structure including a base material (11), a hard coat layer (12), and an anti-reflection layer (13). The luminous reflectance at the side of the anti-reflection layer (13) is 2% or lower. The anti-reflection layer (13) has a surface (13a) with a coefficient of dynamic friction of 0.3 or lower, and a coefficient of static friction of 0.3 or lower. Furthermore, the difference between the haze value (%) of the anti-reflection film (X) after a scratch test, which is performed on the surface (13a) using steel wool #0000 as a scratching material, under conditions in which the load is 200 g/cm2, the scratching stroke length is 10 cm, and the reciprocation frequency is 1000, and the haze value (%) before said scratch test is 0.1 or lower. This anti-reflection film is suitable for achieving excellent anti-reflection properties and high scratch resistance.
(FR) L'invention concerne un film antireflet (X) qui a une structure stratifiée comprenant un matériau de base (11), une couche de revêtement dur (12) et une couche antireflet (13). La réflectance lumineuse sur le côté de la couche antireflet (13) est de 2 % ou moins. La couche antireflet (13) a une surface (13a) ayant un coefficient de frottement dynamique de 0,3 ou moins, et un coefficient de frottement statique de 0,3 ou moins. En outre, la différence entre la valeur de trouble (%) du film antireflet (X) après un essai de rayage, qui est effectué sur la surface (13a) à l'aide de laine d'acier n°0000 en tant que matériau de rayage, dans des conditions dans lesquelles la charge est de 200 g/cm2, la longueur de course de rayage est de 10 cm et la fréquence de mouvement de va-et-vient est de 1000, et la valeur de trouble (%) avant ledit essai de rayage est de 0,1 ou moins. Ledit film antireflet est approprié pour obtenir d'excellentes propriétés antireflet et une résistance élevée aux rayures.
(JA) 本発明の反射防止フィルム(X)は、基材(11)と、ハードコート層(12)と、反射防止層(13)とを含む積層構造を有し、反射防止層(13)側の視感反射率が2%以下である。反射防止層(13)は、動摩擦係数0.3以下および静止摩擦係数0.3以下の表面(13a)を有する。また、反射防止フィルム(X)において、スチールウール#0000を擦り材として用いて荷重200g/cm2、擦りストローク長10cm、および往復動回数1000の条件で表面(13a)に対して行われる擦り試験の後のヘーズ値(%)の、当該擦り試験より前のヘーズ値(%)に対する差は、0.1以下である。このような反射防止フィルムは、高い反射防止性とともに高い耐擦傷性を実現するのに適する。
