Title
(EN) TRANSPARENT TWO-SIDED ADHESIVE SHEET
(FR) FEUILLE ADHÉSIVE DOUBLE FACE TRANSPARENTE
(JA) 透明両面粘着シート
Abstract
(EN) Disclosed is a transparent two-sided adhesive sheet which has excellent traceability for uneven or lumpy surfaces of printed parts when the adhesive sheet is adhered onto a material of interest, and also has excellent workability such as cutting properties. The transparent two-sided adhesive sheet is characterized by comprising an intermediate resin layer (A) and pressure-sensitive adhesive agent layers (B) that serve as a front surface layer and a back surface layer, wherein each of the layers contains at least one (meth)acrylic acid ester (co)polymer as a base resin, the intermediate resin layer (A) has a larger shear storage modulus (G'(A)) than those of the pressure-sensitive adhesive agent layers (B) at a temperature of 0 to 100˚C and a frequency of 1 Hz, and the indentation hardness (Asker C2 hardness) of the whole of the sheet is 10 to 80.
(FR) L'invention concerne une feuille adhésive double face transparente qui possède d'excellentes caractéristiques d'adaptation à la forme des surfaces irrégulières ou inégales de pièces imprimées lorsque la feuille adhésive est collée sur un matériau d'intérêt, et qui possède également une excellente maniabilité, telle que des propriétés de découpage. La feuille adhésive double face transparente est caractérisée en ce qu'elle comprend une couche de résine intermédiaire (A) et des couches d'agent adhésif sensible à la pression (B) qui font office de couche de surface avant et de couche de surface arrière. Chacune des couches contient au moins un (co)polymère d'ester d'acide (méth)acrylique en tant que résine de base. La couche de résine intermédiaire (A) présente un module de conservation en cisaillement (G'(A)) supérieur à ceux des couches d'agent adhésif sensible à la pression (B) à une température de 0 à 100˚C et à une fréquence de 1 Hz, et la dureté par indentation (dureté Asker C2) de l'ensemble de la feuille est de 10 à 80.
(JA)  被着体へ貼合する際に、印刷部位による段差や凹凸への追随性に優れているばかりか、裁断加工性等の作業性にも優れた透明両面粘着シートを提供する。 中間樹脂層(A)と、表裏面層としての感圧接着剤層(B)とを有する透明両面粘着シートであって、各層はいずれも、1種類以上の(メタ)アクリル酸エステル系(共)重合体をベース樹脂とする層であり、温度範囲0℃~100℃において、周波数1Hzにおける中間樹脂層(A)の貯蔵剪断弾性率(G'(A))が、感圧接着剤層(B)より高く、且つ、シート全体の押込硬度(アスカーC2硬度)が10~80であることを特徴とする透明両面粘着シートを提案する。
