PROBLEM TO BE SOLVED: To provide a thermoplastic elastomeric composition for two color molding that has excellent fluidity on molding and resistance to scratching. SOLUTION: This thermoplastic elastomeric composition for two color molding comprises 10 to 40 wt.% of the component (A), 5 to 40 wt.% of the component (B) and 20 to 80 wt.% of the component (C), wherein the total of (A), (B) and (C) is set to 100 wt.%. In this case, (A) is poly-propylene resin, (B) is a vinyl aromatic compound-conjugated diene copolymer that is hydrogenated under the conditions satisfying (a) and (b), wherein (a) the weight ratio of the vinyl aromatic compound in the vinyl aromatic compound-conjugated diene copolymer is 5 to 20%, (b) the amount of vinyl bonds in the conjugated diene part exceeds 50%. (C) is ethylene-α-olefin copolymer. COPYRIGHT: (C)2008,JPO&INPIT
