LIGHT DIFFUSING STYRENE RESIN MULTILAYER PLATE

摘要

Disclosed is a light diffusing styrene resin multilayer plate comprising a substrate layer (A) and a coating layer (B) containing a styrene resin or a (meth)acrylate-styrene resin and arranged on one or both sides of the substrate layer (A). The substrate layer (A) contains a rubber-modified styrene resin containing a styrene polymer forming the matrix and rubbery polymer particles dispersed, like islands, in the matrix. The cross section of each rubbery polymer particle has a sea-island structure containing the styrene polymer particle inside. The rubber-modified styrene resin is composed of 1-10% by weight of the rubbery polymer and 99-90% by weight of the styrene polymer, and the particle diameter of the rubbery polymer particles is 1.0-5.0 µm. The value of "weight of the styrene polymer/weight of the rubbery polymer" in the methylethylketone insoluble fraction of the rubber-modified styrene resin is within the range of 0.5-1.5.
