<P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition capable of forming an optical pressure-sensitive adhesive film that is an optical pressure-sensitive adhesive film for attachment to an optical element, such as a glass member for a liquid crystal cell, has excellent reworkability from the glass member for a liquid crystal cell and adherend-staining properties, has excellent heat resistance and resistance to moist heat after attachment, and further has good antistatic properties. <P>SOLUTION: The pressure-sensitive adhesive composition contains a composite resin (X) including an acrylic resin (A) having a hydroxyl group and/or a carboxyl group and a glass transition temperature of -60 to 10°C and an urethane urea resin (B) having a glass transition temperature of -60 to 50°C; a crosslinking agent (C) having a functional group reactive to the acrylic resin (A) and/or the urethane urea resin (B); an ionic compound (D); and a silane coupling agent (E), wherein the resin (B) is obtained by reacting a polyamino compound (b3) with an urethane polymer obtained by the reaction of a polyol (b1) having a polyalkylene oxide backbone and a polyisocyanate (b2). <P>COPYRIGHT: (C)2012,JPO&INPIT |
