PROBLEM TO BE SOLVED: To provide an active energy ray-curable adhesive composition capable of firmly bonding a polyvinyl alcohol-based polarizing film to a thermoplastic norbornene-based resin film in a short time, and a polarizing plate manufactured by the lamination using the adhesive composition. SOLUTION: The active energy ray-curable adhesive composition comprises (a) 10-40 pts.wt. (meth)acrylic compound having≥2 (meth)acryloyl groups in the molecule, (b) 15-45 pts.wt. (meth)acrylic compound having a hydroxy group and having only one polymerizable double bond in the molecule and (c) 35-45 pts.wt. (meth)acrylic compound represented by general formula [1] [wherein R1 is a hydrogen atom or a methyl group; R2 is a 2-6C alkylene group; R3 is a phenyl group or alkylene(1-12C alkylene)phenyl group; n is a real number of 2-17] in 100 pts.wt. total amount of the (meth)acrylic compounds. The polarizing plate is obtained by using the adhesive composition. COPYRIGHT: (C)2008,JPO&INPIT
