<P>PROBLEM TO BE SOLVED: To provide an adhesive composition which has a long pot life, excels in workability, attains to practical adhesive performance in a short aging time, and excels in productivity. <P>SOLUTION: The adhesive composition includes: 100 pts.mass of a (meth)acrylic copolymer (A) having a weight average molecular weight of 100,000-2,000,000 and including a monomer component comprising 0-9 pts.mass of a carboxyl group-containing monomer (a-1), 0-9 pts.mass of a hydroxyl group-containing (meth)acrylic monomer (a-2), and 99.9-82 pts.mass of a (meth)acrylic acid ester monomer (a-3), a total amount of the carboxyl group-containing monomer (a-1) and the hydroxyl group-containing (meth)acrylic monomer (a-2) being greater than 0 pts.mass and a total amount of the carboxyl group-containing monomer (a-1), the hydroxyl group-containing (meth)acrylic monomer (a-2), and the (meth)acrylic acid ester monomer (a-3) being 100 pts.mass; 0.01-1 pts.mass of a peroxide crosslinking agent (B), based on 100 pts.mass of the (meth)acrylic copolymer (A); and 0.05-5 pts.mass of a carbodiimide crosslinking agent (C), based on 100 pts.mass of the (meth)acrylic copolymer (A). <P>COPYRIGHT: (C)2012,JPO&INPIT |
