Abstract
A polypropylene resin composition which comprises (A) 100 parts by weight of polypropylene, (B) 20-50 parts by weight of at least one elastomer selected from an ethylenic elastomer, an hydrogenated styrene-butadiene copolymer and a hydrogenated styrene-isoprene block copolymer, (C) 0.3.about.20 parts by weight of polycarbonatediol having a skeleton of aliphatic carbonate with both terminals being a hydroxyl group and (D) 0.about.50 parts by weight of an inorganic filler. The resin composition can provide a molded article having a good adhesive property to a film applied thereon without pretreatment by a halogen-containing solvent.
