Title (EN) HARD COAT FILM
(FR) FEUIL DUR
(JA) ハードコートフィルム
Abstract:
(EN) The purpose of the present invention is to provide a hard coat film which shows excellent temporal adhesion and high durability of a hard coat layer both under normal conditions and hot and humid conditions, even in the case of bonding to a base film having few polar groups and showing poor adhesion, for example, a cycloolefin film. The hard coat film according to the present invention, wherein a hard coat layer comprising an ionizing radiation curable resin is formed on at least one face of a base film, is characterized in that the ionizing radiation curable resin satisfies requirement (I). Requirement (I): peak area ratio 1 ((A/C)×100) is 5% or greater (wherein: A represents a peak area appearing within 3250-3500 cm-1 in infrared spectrometric measurement of the ionizing radiation curable resin in an uncured state; and C represents a peak area appearing within 1650-1800 cm-1 therein).
(FR) La présente invention concerne un feuil dur qui présente une excellente adhérence dans le temps et une grande durabilité d'une couche de revêtement dure, tant dans les conditions normales que dans des conditions chaudes et humides, même dans le cas d'une liaison à un feuil de base ayant un petit nombre de groupes polaires et présentant une mauvaise adhérence, par exemple un feuil de cyclooléfine. Le feuil dur selon la présente invention, une couche de revêtement dur comprenant une résine durcissable par rayonnement ionisant étant formée sur au moins une face d'un feuil de base, est caractérisé en ce que la résine durcissable par rayonnement ionisant satisfait à l'exigence (I). Exigence (I) : le rapport des aires des pics 1 ((A/C)×100) est de 5 % ou plus (A représentant une aire du pic apparaissant dans la gamme de 3250 à 3500 cm-1 dans une mesure au spectromètre infrarouge de la résine durcissable par rayonnement ionisant à l'état non durci ; et C représente une aire du pic apparaissant dans la gamme de 1650 à 1800 cm-1).
(JA) 本発明は、シクロオレフィンフィルム等の極性基が少なく密着性に劣る基材フィルムに対しても、通常条件下、及び耐湿熱条件下におけるハードコート層の経時密着性と耐久性に優れるハードコートフィルムを提供することを目的とする。 本発明のハードコートフィルムは、基材フィルムの少なくとも片面に、電離放射線硬化型樹脂を含有するハードコート層を設けたハードコートフィルムであって、該電離放射線硬化型樹脂が下記条件(I)を満たすことを特徴とする。 条件(I):ピーク面積比1(A/C×100)が5%以上 (但し、未硬化の電離放射線硬化型樹脂の赤外分光スペクトル測定で3250~3500cm-1に現れるピーク面積をAとし、1650~1800cm-1に現れるピーク面積をCとする。)
