<p>PROBLEM TO BE SOLVED: To provide a polypropylene resin composition that has excellent scratch resistance, wear resistance and bleed resistance.SOLUTION: The polypropylene resin composition contains a polypropylene resin and a surface-property-improver composition. The surface-property-improver composition contains: (A) ethylene-α-olefin copolymer rubber, or ethylene-α-olefin-non-conjugated diene copolymer rubber; (B) ethylene-vinyl copolymer; (C) fatty acid amide; and (D) graft copolymer. The (B) includes ethylene, and vinyl monomer that contains oxygen atom. The (D) has (d1) ethylene-acrylic acid alkyl ester copolymer as the main chain and (d2) vinyl copolymer as the side chain. The vinyl monomer that constitutes (d2) includes three kinds of vinyl monomers whose polarities are different.</p> |
