摘要： The pressure-sensitive adhesive sheet of the invention is free from the troubles of forming blisters due to the gas emission from the substrate surface to which the adhesive sheet is applied and bonded by using a unique pressure-sensitive adhesive to form the adhesive layer on a base sheet. The principal ingredient of the pressure-sensitive adhesive used in the present invention is a copolymer having a specified molecular weight and a specified glass transition temperature and composed of (a) from 50 to 85% by weight of a first monomeric moiety of an acrylic ester, e.g., 2-ethylhexyl acrylate, (b) from 1 to 30% by weight of a second monomeric moiety of an acrylic compound having a polar group, e.g., acrylic acid, and (c) from 5 to 40% by weight of a third monomeric moiety of a macromonomer having a polymeric molecular chain of styrene units and/or methyl methacrylate units and having a polymerizable functional group, e.g., methacryloyl group, at the molecular chain end.
摘要翻译：本发明的压敏粘合片由于通过使用独特的压敏粘合剂从粘合片施加和粘结的基材表面的气体排出而形成泡罩的问题，从而在粘合剂层上形成粘合剂层基板。本发明中使用的压敏粘合剂的主要成分是具有特定分子量和规定的玻璃化转变温度的共聚物，由（a）50-85重量％的丙烯酸酯的第一单体部分例如丙烯酸2-乙基己酯，（b）1至30重量％的具有极性基团的丙烯酸化合物的第二单体部分，例如丙烯酸，和（c）5至40重量％的在分子链末端具有苯乙烯单元和/或甲基丙烯酸甲酯单元的聚合物分子链和具有可聚合官能团例如甲基丙烯酰基的大分子单体的第三单体部分。
