<p>PURPOSE: An adhesive composition is provided to improve the productivity of spreading process, and to maintain adhesion under severe condition of high temperature, and high humidity. CONSTITUTION: An adhesive composition comprises a carboxy group-containing acrylic copolymer, a polyol, a crosslinking agent, and a catalyst. The acrylic copolymer is copolymer of a C4-12 alkyl(meth)acrylate monomer, and a carboxylic-containing polymerizable monomer. The weight average molecular weight of the carboxylic-containing polymerizable monomer is 100,000-1,700,000. The polyol is one or more kinds selected from a group consisting of polyacryl polyol, polyether polyol, polyester polyol, polycarbonate polyol, and polycaprolactone polyol.</p> |
