<P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive, excellent in adhesiveness with optical laminates, especially between polarizing plates and glass substrates, even under the conditions of high temperature and high humidity or repeated environmental changes between a low temperature and a high temperature, so as not to cause foaming and peeling between pressure-sensitive adhesive layers and glass substrates, and excellent in durability to prevent a light-leaking phenomenon caused by contraction of a polarizing film, and the like. <P>SOLUTION: A pressure-sensitive adhesive composition [I], including an acrylic resin (A1) having a hydroxy group in its side chain, an acrylic resin (A2) having a carboxy group in its side chain, and an aromatic polyvalent isocyanate-based crosslinker (B), is crosslinked by means of the crosslinker (B) to obtain a pressure-sensitive adhesive, wherein the amount of the crosslinker (B) to be compounded is 0.3-5 pts.wt. based on 100 pts.wt. of the total amount of (A1) and (A2), and the gel fraction is 40-90%. <P>COPYRIGHT: (C)2011,JPO&INPIT |
