发明名称 ADHESIVE COMPOSITION FOR POLARIZING PLATES, POLARIZING PLATE WITH ADHESIVE USING SAME, AND LIQUID CRYSTAL DISPLAY DEVICE USING SAME
摘要 Provided is an adhesive composition for polarizing plates, which is used for adhering polarizing plates, and which exhibits excellent durability even under high-temperature and high-moisture conditions, and which minimizes the occurrence of white streaks. Also provided are a polarizing plate with adhesive and liquid crystal display device using said adhesive composition. The adhesive composition for polarizing plates contains the following: (A) carboxyl group [CG]-containing (meth)acrylic copolymer [MACP] using 1.5 to 3 wt % CG-containing (meth)acrylic monomer [MAM] and 97 to 98.5% MAM not having a reactive functional group; (B) CG- and hydroxyl group [HG]-containing MACP using 0.5 to 3 wt % CG-containing MAM, 0.3 to 1 wt % HG-containing MAM, and 96 to 99.2 wt % MAM not having a reactive functional group; (C) toluene diisocyanate-type isocyanate compound; and (D) a silane coupling agent. The respective weight average molecular weight of (A) and (B) fall within the range of 950,000 to 1,050,000, the weight ratio of (A)/(B) falls within the range of 70/30 to 90/10, and (C) is contained in a ratio of 10 to 20 parts by weight with respect to 100 parts by weight of the total weight of MACP.
