Title (EN) DOUBLE-SIDED ADHESIVE SHEET
(FR) FEUILLE ADHÉSIVE DOUBLE FACE
(JA) 両面粘着シート
Abstract:
(EN) Provided is a double-sided adhesive sheet which is provided with a foam substrate, and which exhibits excellent releasability from an object to be bonded. The present invention provide a double-sided adhesive sheet which has a first surface and a second surface, both serving as adhesive surfaces, and which comprises a sheet-like foam substrate, a first cover part that is arranged on a first side of the foam substrate, and a second cover part that is arranged on a second side of the foam substrate. The first cover part comprises an adhesive layer which is exposed in the first surface and a reinforcement layer which is bonded to the adhesive layer. The second cover part comprises an adhesive layer which is exposed in the second surface.
(FR) L'invention concerne une feuille adhésive double face qui est pourvue d'un substrat en mousse, et qui présente une excellente aptitude au décollement d'un objet à coller. La présente invention concerne une feuille adhésive double face qui a une première surface et une seconde surface, toutes deux servant de surfaces adhésives, et qui comprend un substrat en mousse de type feuille, une première partie de couverture qui est disposée sur un premier côté du substrat en mousse, et une seconde partie de couverture qui est disposée sur un second côté du substrat en mousse. La première partie de couverture comprend une couche adhésive qui est rendue visible dans la première surface et une couche de renforcement qui est liée à la couche adhésive. La seconde partie de couverture comprend une couche adhésive qui est rendue visible dans la seconde surface.
(JA) 発泡体基材を備え、被着体からの剥離性に優れた両面粘着シートを提供する。本発明により提供される粘着シートは、第一表面および第二表面がいずれも粘着面となっている両面粘着シートであって、シート状の発泡体基材と、上記発泡体基材の第一面側に配置された第一被覆部と、上記発泡体基材の第二面側に配置された第二被覆部と、を含む。上記第一被覆部は、上記第一表面に露出する粘着剤層と該粘着剤層と結合して設けられている補強層とを含む。上記第二被覆部は、上記第二表面に露出する粘着剤層を含む。
