<P>PROBLEM TO BE SOLVED: To provide an antibacterial polycarbonate resin composition excellent in color development and heat stability. <P>SOLUTION: The antibacterial polycarbonate resin composition comprises 100 pts.wt. of a polycarbonate resin (A); 0.05-1.5 pts.wt of an antibacterial agent (B) comprising an amorphous aluminosilicate characterized by holding a metal ion; 0.02-1.0 pt.wt. of a phosphorus-based antioxidant (C); 0.02-1.0 pt.wt. of a phenolic antioxidant (D); and 0-0.001 pt.wt. of a colorant (E). The antibacterial polycarbonate resin composition has less initial discoloration and further has excellent stability even when subjected to thermal history in a molding process, so that the hue of a molding thereof is excellent, and furthermore, has remarkably excellent color development when subjected to coloring, so that the molding thereof with rich designability is obtained. Therefore, the antibacterial polycarbonate resin composition is suitably used in components of antibacterial home electronics, information-related equipment, stationery, miscellaneous goods, and the like which require designability, so that the practical utility value thereof is very high. <P>COPYRIGHT: (C)2012,JPO&INPIT |
