PURPOSE:To obtain an automotive member which shows a good adhesion to a coating film even when coated directly with a coating material and has high mechanical strengths and durability by molding a resin compsn. comprising a specific ethylene-propylene copolymer and a plurality of specific components. CONSTITUTION:A molded article is prepd. by molding a resin compsn. comprising 40-79.99wt.% ethylene-propylene copolymer having an ethylene content of 3-25wt.% and an MFR of 5-120g/10min and contg. 3-35wt.% matters which are sol. in xylene at room temp. and contain 20-70wt.% ethylene; 20-50wt.% elastomer selected from the group consisting of an ethylenic elastomer, a hydrogenated butadiene-styrene block copolymer, and a hydrogenated isoprene-styrene block copolymer; 0.01-10wt.% (hydrogenated) hydroxyl-terminated diene polymer; and 1-30wt.% filler selected from the group consisting of a flaky filler having a specific surface area of 30000cm<2>/g or higher, a length of 15mum or lower, a mean particle diameter of 0.2-3mum, and a mean aspect ratio of 4 or higher and a fibrous filler having a mean diameter of 2mum or lower and a mean aspect ratio of 5 or higher. A coating film is formed directly on the surface of the article to give an automotive member. |
