<p>PURPOSE: An adhesive composition comprises excellent workability because of long pot life and excellent workability and to reach to a usable adhesive performance in short measuring time after adhesive process, and to have excellent productivity. CONSTITUTION: An adhesive composition comprises: 100.0 parts by weight of a (meth)acryl copolymer(A) with a weight average molecular weight of 100,000-2,000,000 g/mol; 0.05-5 parts by weight of carbodiimide cross-linking agent(B); and 0.01-0.3 parts by weight of a coupling agent. The coupling agent is a titanium coupling agent, a zirconium coupling agent or a hafnium coupling agent. An adhesive composition additionally comprises 0.05-5 parts by weight of an isocyanate-based crosslinking agent(D) based on 100.0 parts by weight of the (meth)acryl copolymer(A). An optical element comprises an adhesive layer formed of the adhesive composition.</p> |
