Title (EN) FUNCTIONAL FILM
(FR) FILM FONCTIONNEL
(JA) 機能性フィルム
Abstract:
(EN) The present invention relates to a functional film that is a laminated body of an amorphous film and a supporting film, or a functional film that is a laminated body in which an amorphous film, an adhesive layer, and a supporting film are directly laminated in this order, wherein the supporting film satisfies the following condition (I): the absolute value of the coefficient of thermal expansion is 0.50% or less, the coefficient of thermal expansion being measured after heating the functional film at a temperature-rising rate of 5°C/min from 25°C to 150°C, and subsequently cooling the functional film at a temperature-dropping rate of 5°C/min from 150°C to 25°C under a tensile load of 50 g/5 mm.
(FR) La présente invention concerne un film fonctionnel qui est un corps stratifié d'un film amorphe et d'un film de support, ou un film fonctionnel qui est un corps stratifié dans lequel un film amorphe, une couche adhésive et un film de support sont directement stratifiés dans cet ordre, le film de support satisfaisant à la condition suivante (I) : la valeur absolue du coefficient de dilatation thermique est de 0,50 % ou moins, le coefficient de dilatation thermique étant mesuré après chauffage du film fonctionnel à un taux d'élévation de température de 5 °C/min de 25 °C à 150 °C, puis refroidissement du film fonctionnel à une vitesse de chute en température de 5 °C/min de 150 °C à 25 °C sous une charge de traction de 50 g/5 mm.
(JA) 非晶性フィルムと支持フィルムとの積層体である機能性フィルム、又は非晶性フィルムと粘着剤層と支持フィルムとをこの順で直接積層した積層体である機能性フィルムであって、前記支持フィルムが下記条件(I) 条件(I):引張荷重50g/5mm条件下、25℃から150℃まで5℃/分の昇温速度で昇温した後、続けて、150℃から25℃まで5℃/分の降温速度で降温させた後に測定される熱膨張率の絶対値が0.50%以下 を満たす、機能性フィルムに関する。
