Abstract
(EN)
A shaped body having a light reflecting surface of a composition containing (a) at least 50 % by weight of an aromatic polycarbonate resin and (b) an auxiliary ingredient in such an amount that the light reflecting surface has a total reflectance of at least 80 % and a diffuse reflectance of at least 75 %. The shaped body is useful as a light reflector.
