<p>PURPOSE: An adhesive composition is provided to have excellent optical resistance and durability in case of using for optical components like a polarizer, etc. CONSTITUTION: An adhesive composition comprises a first (meth)acrylic acid ester polymer of which average molecular weight is 700,000-2,500,000, a second (meth)acrylic acid ester polymer of which average molecular weight is 8,000-250,000, and a crosslinking agent. The ratio of the second (meth)acrylic acid ester polymer to the first (meth)acrylic acid ester polymer is 5-40 parts by weight. The second (meth)acrylic acid ester polymer contains a monomer including a functional group reactable with the crosslinking agent.</p> |
