Abstract

Disclosed is a multilayer sheet which is excellent in dimensional stability, light resistance and light diffusion. Specifically disclosed is a sheet having a multilayer structure wherein a front layer (a) and a back layer (c) are mainly composed of the component (A) below, and an intermediate layer (b) is mainly composed of the component (B) below. Component (A): A styrene resin composition containing 100 parts by mass of a styrene copolymer composed of 20-50% by mass of a styrene monomer unit and 80-50% by mass of a (meth)acrylate monomer unit, 1-10 parts by mass of an unmelted compound having a refractive index difference with the styrene copolymer of not more than 0.005 and an average particle diameter of 5-15 m, 0.1-2 parts by mass of a hindered amine compound, and 0.1-2 parts by mass of a benzotriazole compound. Component (B): A resin composition containing 100 parts by mass of a styrene copolymer and 1-10 parts by mass of an unmelted compound having a refractive index difference with the styrene copolymer of 0.05-0.14 and an average particle diameter of 2-10 m.
