Abstract: The present invention relates to a light diffusing composition and its use for imparting light diffusing properties to a thermoplastic polymer. The present invention further relates to a polymer composition containing said novel light diffusing composition and to a compounded composition or formed article produced therefrom such as a cover. Said thermoplastic light diffusing composition comprises a) an inorganic particle, b) a polymeric particle differs in refractive index n at 589 nm by at least 0.05 from that of the thermoplastic resin polymer, and one or more of c), d), or mixtures thereof wherein c) is a wavelength downshifting material, and d) is an interference pigment. Further, the present invention relates to a luminous device comprising a light source, preferably one or more LED and a formed cover comprising said light diffusing composition.
