<p><P>PROBLEM TO BE SOLVED: To provide an adhesive composition which is excellent in transparency and adhesion with an ITO layer while preventing breaching under high temperatures and high humidity. <P>SOLUTION: The adhesive composition includes: a (meth)acrylic polymer (A) including a structural unit derived from a (meth)acrylic alkyl ester and a structural unit derived from a monomer having hydroxyl, the ratio of which to the total mass of all structural units is 10-50 mass%; and a (meth)acrylic oligomer (B) including a structural unit derived from a (meth)acrylic alkyl ester and a structural unit derived from a monomer having hydroxyl, the ratio of which to the total mass of all the structural units is 10-50 mass%, the oligomer having a weight average molecular weight of 2,500-10,000. At least one of the polymer (A) and the oligomer (B) includes a structural unit derived from a polar group-containing monomer including at least one of amino, amide and alkoxy, and the ratio of the structural unit derived from the polar group-containing monomer in the polymer (A) or oligomer (B) is 6-50 mass% relative to the total mass of all the structural units. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
