Abstract
(EN) Provided are an acrylic adhesive agent capable of realizing both exceptional bending properties and exceptional recovery properties with respect to a bending motion in a low-temperature environment, an acrylic adhesive agent composition for forming the acrylic adhesive agent, an adhesive film having an adhesive agent layer configured from the acrylic adhesive agent, and a flexible device comprising the adhesive film.　The acrylic adhesive agent according to an embodiment of the present invention is such that the adhesive force with respect to a polyimide film is 5.0 N/25 mm or greater at a peel rate of 300 mm/min and a peel angle of 180 degrees at 23°C, wherein the creep value at -20°C is 70% or greater, and the recovery value at -20°C is 70% or greater.
(FR) L'invention concerne un agent adhésif acrylique capable de réaliser à la fois des propriétés de flexion exceptionnelles et des propriétés de récupération exceptionnelles par rapport à un mouvement de flexion dans un environnement basse température, une composition d'agent adhésif acrylique pour former l'agent adhésif acrylique, un film adhésif ayant une couche d'agent adhésif configurée à partir de l'agent adhésif acrylique, et un dispositif flexible comprenant le film adhésif.　Selon un mode de réalisation de la présente invention, l'agent adhésif acrylique est tel que la force adhésive par rapport à un film de polyimide est au moins 5,0 N/25 mm à une vitesse de pelage de 300 mm/minute et un angle de pelage de 180 degrés à 23°C, la valeur de fluage à -20°C étant au moins 70 %, et la valeur de récupération à -20 °C étant au moins 70%.
(JA) 低温環境下において、屈曲動作に対する優れた屈曲性と優れた回復性を両立して発現できるアクリル系粘着剤、該アクリル系粘着剤を形成するアクリル系粘着剤組成物、該アクリル系粘着剤から構成される粘着剤層を有する粘着フィルム、及び、該粘着フィルムを備えるフレキシブルデバイスを提供する。　本発明の実施形態によるアクリル系粘着剤は、２３℃における、剥離速度３００ｍｍ／分、剥離角度１８０度での、ポリイミドフィルムに対する粘着力が５．０Ｎ／２５ｍｍ以上であるアクリル系粘着剤であって、－２０℃におけるクリープ値が７０％以上であり、－２０℃におけるリカバリー値が７０％以上である。
