<P>PROBLEM TO BE SOLVED: To provide a weather-resistant film which has high mechanical strength and weather resistance, specifically, exhibiting no discoloration and no decrease in designability even in a long period usage in a severe environment such as outdoors where sun light is directly radiated. <P>SOLUTION: The weather-resistant film is obtained by molding a thermoplastic resin composition prepared by blending 1 to 45 parts by mass of an inorganic pigment (B) with 100 parts by mass of a rubber-reinforced aromatic vinylic resin (A), wherein the rubber-reinforced aromatic vinylic resin (A) contains a graft copolymer resin (A-1) obtained by polymerizing a vinylic monomer (b) containing an aromatic vinyl compound in the presence of a silicone-acrylic composite rubber (a), and as required, a (co)polymer (A-2) of a vinylic monomer (b); and the content of the silicone-acrylic composite rubber (a) with respect to 100 mass% of the rubber-reinforced aromatic vinylic resin (A) is 5 to 30 mass%, and the content of the aromatic vinyl compound unit is 5 to 40 mass%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
