<P>PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition and the resin molded article of the composition, having not only excellent designing property, scratch resistance and impact resistance but high crack generation energy and superior strength against impact on the surface. <P>SOLUTION: The thermoplastic resin composition comprises 20 to 80 pts.wt of an acrylic resin (A), 15 to 50 pts.wt of a grafted copolymer (B) obtained by graft polymerization of a (meth)acrylic acid ester monomer and other monomers which can be copolymerized with the (meth)acrylic acid ester monomer in the presence of a rubber polymer, and 5 to 65 pts.wt of a copolymer (C) including a copolymer (C-1) and a copolymer (C-2). Each 100 pts.wt of the copolymer (C-1) and the copolymer (C-2) are obtained by copolymerizing 20 to 28 pts.wt of a vinyl cyanide monomer and 72 to 80 pts.wt of other monomers which can be copolymerized with the vinyl cyanide monomer, and the difference in the content of vinyl cyanide monomers between the copolymer (C-1) and the copolymer (C-2) is 3 pts.wt or more. <P>COPYRIGHT: (C)2012,JPO&INPIT |
