PROBLEM TO BE SOLVED: To provide an adhesive composition for optical film satisfying durability with no generating foaming, peeling or humidified white turbidness, capable of suppressing display unevenness due to light leak and forming an adhesive layer excellent in metal corrosion resistance, to a glass and a transparent conductive layer.SOLUTION: There is provided an adhesive composition for optical film containing a (meth)acryl polymer (A) containing alkyl (meth)acrylate (a1) of 70 wt.%, aromatic ring-containing (meth)acrylate (a2) of 3 to 25 wt.%, amide group-containing monomer (a3) of 0.1 to 8 wt.%, carboxyl group-containing monomer (a4) of 0.01 to 2 wt.% and hydroxyl group-containing monomer (a5) of 0.01 to 3 wt.% as monomer units, having a weight average molecular weight (Mw) of 1,000,000 to 2,500,000 and satisfying Mw/number average molecular weight (Mn) of 1.8 to 10, and a crosslinking agent (B) of 0.01 to 3 pts.wt. based on 100 pts.wt. of the (meth)acryl polymer. |
