Title (EN) TRANSPARENT ADHESIVE FILM
(FR) FILM ADHÉSIF TRANSPARENT
(JA) 透明粘着フィルム
Abstract:
(EN) The purpose of the present invention is to provide a transparent adhesive film difficult to be visually recognized, that is, hardly conspicuous, thereby having little influence on the design property of an adherend. The present invention relates to a transparent adhesive film provided with a base material having an uneven surface, and an adhesive layer laminated on a surface opposite to the uneven surface of the base material, wherein an average interval Sm between irregularities on the uneven surface of the base material is 45 μm or more, an average inclination angle θm of the irregularities on the uneven surface of the base material is 0.5-15°, and the gloss GL of the uneven surface of the base material is 60% or less.
(FR) La présente invention vise à fournir un film adhésif transparent difficile à reconnaître visuellement, c'est-à-dire difficilement visible, ce qui a peu d'influence sur la propriété de conception d'une partie adhérée. La présente invention concerne un film adhésif transparent comportant un matériau de base ayant une surface irrégulière, et une couche adhésive stratifiée sur une surface opposée à la surface irrégulière du matériau de base, un intervalle moyen Sm entre des irrégularités sur la surface irrégulière du matériau de base étant de 45 µm ou plus, un angle d'inclinaison moyen θ m des irrégularités sur la surface irrégulière du matériau de base étant de 0,5 à 15°, et le brillant GL de la surface irrégulière du matériau de base étant inférieur ou égal à 60 %.
(JA) 本発明は、視認されにくい、即ち目立ちにくいことから、被着体の意匠性に与える影響が少ない透明粘着フィルムを提供することを目的とする。本発明は、凹凸面を有する基材と、前記基材の前記凹凸面の反対側の面に積層された粘着剤層とを備え、前記基材の前記凹凸面における凹凸の平均間隔Smが45μm以上であり、前記基材の前記凹凸面における凹凸の平均傾斜角θaが0.5°以上15°以下であり、前記基材の前記凹凸面における60°光沢度GLが60%以下である透明粘着フィルムに関する。
