PURPOSE:A propylene resin composition that is composed of crystalline propylene resin, styrene-butadiene block copolymer or ethylene-vinyl acetate copolymer and talc, thus having high mechanical characteristics and high coating film adhesion. CONSTITUTION:(A) 45-90wt% of a crystalline propylene resin of 0.5-20MI, which is measured at 230 deg.C and 2.16kg, and less than 20wt% ethylene content, (B) 5-25wt% of a styrene-butadiene block copolymer of 20-65wt% styrene content or an ethylene-vinyl acetate copolymer of 1-30MI and 10-30wt% vinyl acetate content and 5-30wt% of talc of 0.5-10mum average particle size are meld kneaded. |
