Abstract: Provided is a material suitable for producing a glass fiber-reinforced molded body with reduced generation of white haze while reducing the amount of a dispersing agent to be used. A glass fiber-reinforced propylene-based resin composition, including 10 to 50 parts by mass of glass fibers; 50 to 90 parts by mass of a propylene-based resin (provided that the both in total is 100 parts by mass); 0.3 parts by mass or more of carbon black; and a polyolefin wax having an average particle size of 1 to 40 ?m in an amount such that a mass ratio of the polyolefin wax to the carbon black is 0.75 to 1.5.

Abstract: A polyolefin-based resin composition and a colored resin pellet having good colorant dispersibility and low fogging properties and particularly preferred for the production of a molded article for an interior article or interior member of an automobile, by dosing 0.01 parts by weight or more and 2.0 parts by weight or less of a colorant including at least one pigment selected from a group consisting of carbon black and an organic pigment, and 0.01 parts by weight or more and 2.0 parts by weight or less of a synthetic wax having an average particle diameter of 1 ?m or more and 40 ?m or less, based on 100 parts by weight of a resin material component including a polyolefin-based resin.

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.
