PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition based on an acrylic block copolymer and free from bleed out and exudation of light stabilizer and being excellent in weather resistance (light resistance). SOLUTION: The thermoplastic elastomer composition is one mainly consisting of an acrylic block copolymer comprising methacrylic polymer blocks (a) and acrylic polymer blocks (b), wherein the acrylic block copolymer is a copolymer with a reactive light stabilizer (c). The composition can give a thermoplastic elastomer excellent in weather resistance (light stability). COPYRIGHT: (C)2009,JPO&INPIT
