PROBLEM TO BE SOLVED: To provide an adhesive composition showing good durability when laminated as an adhesive layer on a surface of an optical member, an adhesive layer comprising the above composition, and an optical member with an adhesive layer including the above adhesive layer.SOLUTION: The adhesive composition comprises: 100 parts by weight of a (meth)acrylic resin (A) that has a content of 3.5 wt.% or less of a structural unit derived from a (meth)acryl monomer having a hydroxyl group and has a glass transition temperature of -25°C or lower; 0.3 to 1 part by weight of an aromatic isocyanate-based crosslinking agent (B); and at least one compound (C) selected from an organic acid salt (C-1) and a compound (C-2) containing an alkylene oxy group. When the composition contains the organic acid salt (C-1), the content of the organic acid salt is 0.0001 to 5 parts by weight, and when the composition contains the compound (C-2) containing an alkylene oxy group, the content of the compound is 0.1 to 5 parts by weight. An adhesive layer comprising the above adhesive composition, and an optical member with an adhesive layer including the above adhesive layer are also provided.SELECTED DRAWING: Figure 1 |
