摘要：Disclosed is a light reflector formed of a biaxially-stretched film which containsa thermoplastic resin and a filler and has an opacity of at least 95%, a whiteness of atleast 90%, a reflectance R0 of at least 92%, and an areal draw ratio of from 22 to 80times, wherein the color difference DELTA EH, after irradiated with a metal halide lampspaced from the light reflector by 10 cm under an environmental condition of 83 DEG Cand a relative humidity of 50% and at an intensity of radiation of 90 mW/cm<2> for 10hours, is at most 10. The reflector is free from the trouble of yellowing as in whitepolyester films heretofore used in reflectors and is stable against color change for along period of time.
