摘要： The present invention relates to an acrylic pressure-sensitive adhesive composition, and more precisely, an acrylic pressure-sensitive adhesive composition which is prepared by copoly-merization of a vinyl and/or acrylic monomer having a cross-linkable functional group and comprises 100 weight part of a high molecular weight (meth)acrylic copolymer which is prepared by copolymerization of a vinyl and/or acrylic monomer harboring a cross-linkable functional group and whose weight average molecular weight is 40˜100 times as high as the entanglement molecular weight, 5˜50 weight part of a low molecular weight (meth)acrylic copolymer which does not contain a cross-linkable functional group and whose weight average molecular weight is 2˜15 times as high as entanglement molecular weight, and 0.01˜10 weight part of a multifunctional cross-linking agent. The acrylic pressure-sensitive adhesive composition of the present invention has reliable adhesion durability under high temperature and high humidity and at the same time reduces the light leakage due to the stress relaxation and enhances the cutting-efficiency of a polarizing plate.
摘要翻译：本发明涉及一种丙烯酸类压敏粘合剂组合物，更确切地说，涉及通过具有可交联官能团的乙烯基和/或丙烯酸单体的共聚合制备并包含100重量份的丙烯酸类压敏粘合剂组合物通过具有可交联官能团的乙烯基和/或丙烯酸单体共聚而得到的高分子量（甲基）丙烯酸共聚物的一部分，其重均分子量为缠结分子量的40〜100倍， 5〜50重量份的不含可交联官能团的低分子量（甲基）丙烯酸共聚物，其重均分子量为缠结分子量的2〜15倍，0.01〜10重量份多功能交联剂。本发明的丙烯酸类粘合剂组合物在高温高湿下具有可靠的粘合耐久性，同时降低了由于应力松弛引起的漏光，提高了偏振片的切割效率。
