LIGHT-DIFFUSING STYRENE-BASED RESIN COMPOSITION AND MOLDING

摘要

PROBLEM TO BE SOLVED: To obtain a light-diffusing styrene-based resin composition having an excellent light diffusion transmittance, slight warpage by water absorption and excellent heat resistance. SOLUTION: The light-diffusing styrene-based resin composition comprises 100 pts.wt of a styrene-based monomer-(meth)acrylic acid-based monomer-based copolymer (A) composed of 90-99 wt.% of a styrene-based monomer and 1-10 wt.% of a (meth)acrylic acid-based monomer and 0.1-10 pts.wt. of an organic crosslinked particle (B) having an absolute value difference of refractive index between the organic crosslinked particle and the styrene-based monomer-(meth)acrylic acid-based monomer-based copolymer (A) of 0.04-0.12 and 1.0-10μm weight-average particle diameter.
