As a monomer unit, 70 weight% or more of alkyl (meth)acrylate (a1), 3 to 25 weight% of aromatic ring containing (meth)acrylate (a2), 0.1 to 8 weight% of amide group containing monomer (a3), carboxyl group containing 0.01 to 2% by weight of the monomer (a4) and 0.01 to 3% by weight of the hydroxyl group-containing monomer (a5) are contained, the weight average molecular weight (Mw) is 1,000,000 to 2.5,000,000, and Mw/number average molecular weight (Mn) containing 0.01 to 3 parts by weight of the (meth)acrylic polymer (A) satisfying 1.8 or more and 10 or less, and the crosslinking agent (B) with respect to 100 parts by weight of the (meth)acrylic polymer (A) A pressure-sensitive adhesive composition for a film. The pressure-sensitive adhesive composition satisfies durability that does not cause foaming, peeling, or humidified cloudiness with respect to glass and transparent conductive layers, can suppress display unevenness due to light leakage, and forms a pressure-sensitive adhesive layer excellent in metal corrosion resistance can do. |
