PROBLEM TO BE SOLVED: To obtain an acrylic block copolymer composition which has excellent weather resistance and does not cause the deterioration of flexibility and discoloration, even when used outdoors over a long period, and to provide an outdoor member comprising the same. SOLUTION: This acrylic block copolymer composition is characterized by compounding a UV light absorbent with an acrylic block copolymer having at least one polymer block (I) comprising an acrylate-based polymer (A1) and at least one polymer block (II) comprising an acrylate-based polymer (A2) having a structure different from the acrylate-based polymer (A1) or a methacrylate-based polymer (B). Herein, a benzotriazole-based UV light absorbent is preferably used as the UV light absorbent. The outdoor member uses the composition. COPYRIGHT: (C)2005,JPO&NCIPI
