PROBLEM TO BE SOLVED: The present invention recognizes the above-mentioned problems and is excellent in adhesiveness including a curved surface to a substrate, particularly a substrate containing a nonpolar polyolefin such as polyethylene or polypropylene, as well as a stainless steel plate, and at the same time, yellowing by heating. It was an object to provide a pressure-sensitive adhesive composition excellent in weather resistance with little change. The present invention includes a (meth) acrylic copolymer (A) and a (meth) acrylic copolymer (B) polymerized using isobornyl (meth) acrylate, The (meth) acrylic copolymer (B) has a constituent unit derived from isobornyl (meth) acrylate having a content unit of 30% by mass or more, thereby providing the pressure-sensitive adhesive composition, which solves the above problems did. |
