PROBLEM TO BE SOLVED: To obtain the subject composition capable of exhibiting excellent weather resistance, extrusion appearance in high temperature molding and printing characteristics by combining and compounding a styrene-based resin mixture having specific compositions with two kinds of stabilizers. SOLUTION: This composition is obtained by including (D) 2-t-butyl-6-(3-t- butyl-2-hydroxy-5-methylbenzyl)-4-methylphenyl acrylate and/or 2-[1-(2- hydroxy-3,5-di-t-pentylphenyl)ethyl]-4,6-di-t-pentylphenyl acrylate and (E) an ultraviolet light absorbent and/or a hindered amine-based light stabilizer into a styrene-based resin mixture comprising (A) 97-70 wt.% rubber-modified styrene- based resin containing 3-15 wt.% rubber-like elastomer as dispersed particles having 0.2-0.9μm disperse particle diameter, (B) 2-15 wt.% petroleum resin and (C) 1-15 wt.% vinyl aromatic hydrocarbon-conjugated diene block copolymer. |
