Industrial Applicability The present invention satisfies the reworkability that allows the optical film to be easily peeled off from the liquid crystal panel or the like, and the durability that does not cause peeling or lifting in the state in which the optical film is bonded. It aims at providing the adhesive composition for optical films which can form the adhesive layer which can improve the display nonuniformity by clouding. In the present invention, as monomer units, 67 to 96.99% by weight of alkyl (meth) acrylate (a1), 1 to 20% by weight of benzyl (meth) acrylate (a2), 2 to 10% by weight of carboxyl group-containing monomer (a3), And 0.01 to 3% by weight of hydroxyl group-containing monomer (a4), having a weight average molecular weight (Mw) of 1.6 million or more, and a Mw / number average molecular weight (Mn) of 1.8 to 10 or less (meth). An acrylic film (A) is contained, The adhesive composition for optical films is provided. |
