(57) [Summary] [Purpose] To provide a polypropylene resin composition having not only excellent paintability but also excellent balance of physical properties represented by impact resistance and rigidity. [Structure] (A) Polypropylene resin, (B) Modified polypropylene resin grafted with at least one kind of monomer containing a carboxylic acid anhydride group or a carboxyl group, and (C) (a) ethylene unit, (B) α, β unsaturated carboxylic acid alkyl ester unit and (c) (D) selected from an amino group, an epoxy group, a dihydrooxazolyl group and an isocyanate group with respect to 100 parts by weight of a total of (A), (B) and (C) of an ethylene copolymer comprising a maleic anhydride unit. A polypropylene resin composition comprising 0.1 to 10 parts by weight of a polyfunctional compound having two or more functional groups in one molecule. |
