Abstract

Disclosed is a resin composition for light diffusion plates, which contains a specific styrene resin and a light-diffusing agent. Also disclosed is a light diffusion plate obtained by molding such a resin composition for light diffusion plates. Specifically, the resin composition for light diffusion plates contains, as the styrene resin, a resin obtained by copolymerizing a hyperbranched macromonomer with a styrene monomer. The hyperbranched macromonomer has a plurality of branches and a plurality of polymerizable double bonds at the end portions of the branches. By using such a resin composition, there can be obtained a light diffusion plate having good light diffusibility and low water absorption, which is suppressed in transmittance variations. In addition, by using such a styrene resin, injection molding which enables to perform molding and surface processing of a light diffusion plate simultaneously can be employed.
