Abstract
To provide a thermoplastic elastomer composition which is excellent in light resistance and flexibility and has high tear strength. [MEANS FOR SOLVING PROBLEMS] A thermoplastic elastomer composition comprising 100 parts by mass of acrylic multi-layer polymer particles (A) which each comprise at least two layers, i.e., at least one inner rubber layer (I) and at least one outermost thermoplastic resin layer (II), 5 to 300 parts by mass of an ethylene/vinyl ester copolymer (B), and 0.5 to 150 parts by mass of a graft copolymer (C) composed of an ethylene/vinyl ester copolymer backbone and a graft bonded to the backbone which consists of units derived from a monomer having a polarity higher than that of the backbone.
