摘要:
Provided is a pressure sensitive adhesive sheet containing, on a substrate or a release material, a resin layer formed of a multilayer structure of three or more layers including a fine particle-containing layer that contains fine particles in an amount of 15% by mass or more, at least a surface (±) of the resin layer being opposite to the side thereof on which the substrate or the release material is provided having pressure sensitive adhesiveness, wherein the fine particle-containing layer is formed not as the outermost layer of the resin layer, and one or more concave portions exist on the surface (±) and the shapes of the one or more concave portions have irregular shapes. When attached to an adherend, the pressure sensitive adhesive sheet can exhibit excellent air escape property of readily removing air accumulation which may be formed, good blister resistance and good pressure sensitive adhesion characteristics.
摘要(中):
本发明提供一种粘合片,其在基材或脱模材料上具有树脂层,所述树脂层由三层以上的多层结构构成,所述三层以上的层包含含有15质量%的微粒的含微粒层,或者 所述树脂层的至少与设置有所述基材或所述剥离材料的一侧相反的面(±)具有压敏粘合性,其中所述含微粒层不是所述基材或所述剥离材料的最外层 树脂层,并且在表面(±)上存在一个或多个凹部,并且一个或多个凹部的形状具有不规则形状。 当粘附到被粘物上时,压敏粘合剂片可显示优异的空气逸出特性,易于除去可能形成的空气积聚,良好的抗起泡性和良好的压敏粘合特性。
