POLYPROPYLENE RESIN COMPOSITION HAVING IMPROVED COATING PROPERTY

摘要

a polypropylene resin composition comprising: (A) a composition of (a) a crystalline ethylene-propylene block copolymer, (b) a thermoplastic elastomer having a substantially saturated main chain, and (c) an inorganic filler; (B) (i) a hindered nitrogen-free phenolic antioxidant; (ii) a nitrogen-containing hindered phenolic antioxidant; (iii) a benzotriazole ultraviolet absorber; and (iv) a hindered amine light stabilizer having a molecular weight of 500 or more or having no N-H bond and having a molecular weight of less than 500, or (i') a hindered phenolic antioxidant; (ii') an organic sulfur type antioxidant; and (iii') a hindered amine light stabilizer having no N-H bond.
