ADHESIVE COMPOSITION FOR POLARIZING PLATES, POLARIZING PLATE WITH ADHESIVE USING SAME, AND LIQUID CRYSTAL DISPLAY DEVICE USING SAME |
摘要 |
<p>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.</p> |
