Abstract

PURPOSE: A light-scattering synthetic resin usable as molding materials, e.g. lighting covers, having high scattering and light transmission properties, comprising fine transparent material powder having a lower reflectance than the matrix resin.
CONSTITUTION: (A) spherical or polyhedral transparent material, e.g. an inorganic material, such as glass or guartz powder, or calcium fluoride, or an organic material, such as polystyrene, polymethl methacrylate, or a fluorinated acrylic ester, having a reflectance 0.01W0.1 lower than the matrix resin and an average particle size of 1W10μ is dispersed in (B) a transparent synthetic resin, e.g. polystyrene, metacrylic resin, polyvinyl chloride, or polycarbonate. The amount of the material (A) is preferably about 10 parts by wt. or less per 100 parts by wt. of the resin (B).
