偏光板的粘性膜及粘着剂组成物、偏光板以及光学显示器
摘要：
本发明提供一种用于偏光板的粘性膜、用于所述偏光板的粘着剂组成物、包含所述粘性膜的偏光板以及包含所述偏光板的光学显示器。用于偏光板的粘性膜由用于偏光板的粘着剂组成物形成，用于偏光板的粘着剂组成物包括环氧化合物和(甲基)丙烯酸酯化合物，其中粘性膜具有如等式1所定义的0.015或小于0.015的FT‑IR峰比率： FT‑IR峰比率＝B/A (1)，其中A为在1724厘米‑1处‑(C＝O)‑键的峰高度，并且B为在1636厘米‑1处‑CH＝CH‑键的峰高度。本发明可获得在粘着性、耐久性以及浸没于水中后的粘着性方面展现良好性质的偏光板。
摘要（英）：

An adhesive composition for a polarizing plate, an adhesive film formed from the same, a polarizing plate including the same, and an optical display including the same are disclosed. The adhesive film for a polarizing plate is formed from an adhesive composition including an epoxy compound and a (meth)acrylate compound, and the adhesive film has an FT-IR peak ratio of about 0.015 or lower as defined by Equation 1. Equation 1 FT-IR peak ratio=B/A  (1) In Equation 1, A is the peak height of the peak attributable to the —(C═O)— bond at 1724 cm−1, and B is the peak height of the peak attributable to the —CH═CH— bond at 1636 cm−1.
