<P>PROBLEM TO BE SOLVED: To provide a resin composition for the reflector of a lighting fixture, from which a molded article with high reflectance can be obtained and which has excellent moldability; to provide the sheet-like reflector of a lighting fixture and a method of manufacturing the sheet-like reflector of the lighting fixture, the reflector having high reflectance, excellent uniformity of thickness in a molded article, high productivity and good formability when the sheet is shaped in secondary processing; and to provide the shaped reflector of a lighting fixture and a method of manufacturing the shaped reflector of the lighting fixture, the reflector having high reflectance, excellent productivity and good dimensional accuracy. <P>SOLUTION: The resin composition is obtained by incorporating titanium oxide in an amount of a predetermined range and an inorganic filler excluding the titanium dioxide in an amount of the predetermined range, into a polypropylene resin or a resin essentially comprising a polypropylene resin. The resin composition is molded by extrusion molding or the like into a sheet-like molded article, and when necessary, the sheet-like molded article is shaped by a secondary processing method such as vacuum forming to obtain a reflector particularly suitable for the lighting fixture using an LED as a light source. <P>COPYRIGHT: (C)2010,JPO&INPIT |
