<P>PROBLEM TO BE SOLVED: To provide a resin composition which is excellent in moldability and gives a reflector for a lamp which excels in surface smoothness, is lightweight, and has further improved heat resistance, and to provide the reflector of a lamp comprising the resin composition. <P>SOLUTION: The resin composition includes an amorphous alicyclic structure containing polymer and an aromatic vinyl-maleimide copolymer, wherein the weight ratio of the amorphous alicyclic structure containing polymer to the aromatic vinyl-maleimide copolymer is 30/70 to 95/5, or preferably is 50/50 to 95/5. Further, the resin composition is such that the aromatic vinyl-maleimide copolymer has at least 160°C of the glass transition temperature and contains the structural unit of a styrene origin, and the structural unit of an N-phenyl maleimide origin. <P>COPYRIGHT: (C)2012,JPO&INPIT |
