  • Polypropylene-based resin composition and molded article
    Patent number: 11359082
    Abstract: Disclosed are: a polypropylene-based resin composition comprising 100 parts by mass of polypropylene-based resin (A) (provided that, when the polypropylene-based resin includes other resins and/or inorganic filler, the total amount of the polypropylene-based resin and other resins and/or inorganic filler is taken as 100 parts by mass), 0.80 to 5.0 parts by mass of on or more types of aluminum flakes (B) having an average particle size of 5 to 90 ?m, and 0.005 to 0.06 parts by mass of carbon black (C); and a molded article obtained by injection-molding this polypropylene-based resin composition. The polypropylene-based resin composition and the molded article obtained from this are excellent in a flip-flop metallic feeling, a heavy luxury feeling, light resistance and a feeling of luminance.
