REFLECTING FILM OF ALIPHATIC POLYESTER RESIN AND REFLECTOR

摘要

[PROBLEMS] To provide a reflecting film which comprises an aliphatic polyester resin, has excellent light reflection characteristics, and does not yellow with time during use. [MEANS FOR SOLVING PROBLEMS] The reflecting film of an aliphatic polyester resin is a reflecting film formed from a resin composition obtained by compounding an aliphatic polyester resin with a finely particulate filler consisting mainly of titanium oxide, wherein the titanium oxide has a niobium content of 500 ppm or lower. The surface of the titanium oxide preferably has been coated with at least one inert inorganic oxide selected among silica, alumina, and zirconia. ® KIPO & WIPO 2007
