Beschreibung
Zusammenfassung:	Provided are an adhesive composition for a polarizing plate, a polarizing plate, and an optical display device, the adhesive composition comprising an epoxy-based compound, a (meth)acrylate-based compound, a photo-acid generator, and an optical radical initiator, the (meth)acrylate-based compound comprising a mixture of a bifunctional (meth)acrylate-based compound and a monofunctional (meth)acrylate-based compound having a hydrophobic functional group, wherein the adhesive strength measured after the adhesive composition for a polarizing plate is separately applied to a PET film, a TAC film, and a COP film, to which a polarizer is then bound, followed by photo-curing, is about 200 gf/inch or more. 本发明提供用于偏光板的粘着剂组成物、偏光板及光学显示器。所述用于偏光板的粘着剂组成物包含环氧类化合物、(甲基)丙烯酸酯类化合物、光酸产生剂及光自由基起始剂。所述(甲基)丙烯酸酯类化合物包括双官能(甲基)丙烯酸酯类化合物与具有疏水性官能基的单官能(甲基)丙烯酸酯类化合物的混合物。当在所述粘着剂组成物沉积至聚对苯二甲酸乙二酯膜、三乙酰纤维素膜及环烯烃聚合物膜中的各者上及将偏光片与其粘结，随后光固化之后所测量时，用于偏光板的粘着剂组成物具有200克力/吋或大于200克力/吋的黏着强度。
