PURPOSE:To obtain a propylene resin composition having excellent rigidity, impact resistance, coating performances, etc., by adding a specific additive to a specified resin composition. CONSTITUTION:(A) 100 pts.wt. resin composition comprising (i) 50-70 pts.wt. propylene-ethylene block copolymer, (ii) 25-35 pts.wt. ethylene-propylene copolymer rubber and (iii) 5-20 pts.wt. talc having 0.5-10mum average particle diameter is blended with (B) 0.01-0.5 pt.wt. tris(3,5-diet-butyl-4-hydroxybenzyl)isocyanurate, (C) 0.03-0.3 pt.wt. compound of formula I (R2 is methyl, t-butyl, etc.; R2 is H, methyl, etc.; R3 is H, methyl, etc.; R4 is as shown for R3; with the proviso that R2 to R4 are not H at the same time), (D) 0.01-0.5 pt.wt. phenyl benzoate-based compound, (E) 0.01-0.5 pt.wt. hexacyclic hindered amine-based compound, (F) 0.01-0.5 pt.wt. compound of formula II (R7 is 5-21C alkyl, etc.; (n) is 1-6) and (G) a compound of formula III (R5 and R6 are H, alkyl, etc.) in an amount corresponding to 1/3 the amount of the component E to give the objective composition. |
