Abstract:
(EN) The present invention provides an optical transparent adhesive sheet which has excellent flexibility and in which occurrence of delayed bubbles is inhibited by use of a thermosetting polyurethane composition from which a thick film can be obtained. The optical transparent adhesive sheet according to the present invention is formed of a cured product of the thermosetting polyurethane composition, has a storage shear elastic modulus (G') of 4.5×103-5.0×104 Pa at 85ºC, a loss tangent (tanδ) of 0.3-0.97 at 85ºC, a thickness of 50-2000 µm, and preferably has an adhesive force of 2 N/25 mm or greater in a 180º peel test.
(FR) La présente invention concerne une feuille adhésive transparente optique qui présente une excellente flexibilité et dans laquelle l'apparition de bulles retardées est évitée par l'utilisation d'une composition de polyuréthane thermodurcissable à partir de laquelle un film épais peut être obtenu. La feuille adhésive transparente optique selon la présente invention est formée d'un produit durci issu de la composition de polyuréthane thermodurcissable, possède un module élastique de conservation en cisaillement (G') de 4,5×103-5,0×104 Pa à 85°C, une tangente de perte (tanδ) de 0,3-0,97 à 85 °C, une épaisseur de 50-2000 µ et possède de préférence une force adhésive de 2 N/25 mm ou plus dans un essai de pelage à 180°.
(JA) 本発明は、柔軟性に優れ、厚膜化が可能な熱硬化性ポリウレタン組成物を用いて、ディレイバブルの発生が抑制された光学透明粘着シートを提供する。本発明の光学透明粘着シートは、熱硬化性ポリウレタン組成物の硬化物からなる光学透明粘着シートであって、85℃での貯蔵せん断弾性率(G')が4.5×10~5.0×10Paであり、かつ、85℃での損失正接(tanδ)が0.3~0.97であり、厚みが50~2000μmであり、好ましくは、180°剥離試験での粘着力が2N/25mm以上である。
