Abstract

The present invention relates to a thermoplastic composition, comprising: A) aromatic polycarbonate and B) Ba) reinforcing fibers and/or Bb) spherical particles of oxides of metals or metalloids of the 3rd main group, 4th main group and/or 4th transition group. The composition further comprises: C) PMMI copolymer and D) phosphite stabilizer and/or phosphine stabilizer, wherein, furthermore, the proportion of B) is ≥35% by weight to ≤40% by weight and the proportion of C) is >0.1% by weight in each case based on the total weight of the composition. The invention further relates to a layered arrangement comprising a substrate layer and a reflection layer distinct from the substrate layer and at least partially covering the substrate layer, wherein the reflection layer at least partially reflects light in the wavelength range from 380 nm to 750 nm, an illumination apparatus comprising a light source and a reflector, wherein the reflector is arranged such that at least a portion of the light transmitted by the light source is reflected by the reflector, and to a process for producing a molded article.
