ALIPHATIC POLYESTER BASED RESIN REFLECTION FILM AND REFLECTION PLATE

摘要

PROBLEM TO BE SOLVED: To provide a reflection film which has an excellent light reflectivity, is reduced in variation in luminance in a surface illuminant, is free from yellowing and deterioration in the light reflectivity with the lapse of time by use, and has an excellent shape retainability. SOLUTION: The aliphatic polyester based resin reflection film is formed of a resin composition containing an aliphatic polyester based resin, titanium oxide and a pulverized filler having a mean particle diameter larger than the mean particle diameter of the titanium oxide. It is preferable that the content of vanadium in the titanium oxide is≤5 ppm. COPYRIGHT: (C)2006,JPO&NCIPI
