Provided is a multilayer sheet having excellent dimensional stability, light resistance, and light diffusivity.n n n As a sheet of a multilayered structure, the surface layer a and the double layer c have the following (A) component as a main component, and the intermediate | middle layer b has the following (B) component as a main component.n n n (A) component: 100 mass parts of styrene-type copolymers which consist of 20-50 mass% of styrene-type monomeric units, and 80-50 mass% of (meth) acrylic-ester type monomeric units, and the difference in refractive index of the styrene-based copolymer are less than 0.005. Styrene system containing 1-10 mass parts of unmelted compound with an average particle diameter of 5-15 micrometers, 0.1-2 mass part of hindered amine type compound, and 0.1-2 mass part of benzotriazole type compound. Resin composition.n n n (B) component: The resin composition which consists of 100 mass parts of styrene-type copolymers, and 1-10 mass parts of unmelted compounds whose average particle diameters are 2-10 micrometers with a refractive index difference of 0.05-0.14. |
