THERMOPLASTIC RESIN COMPOSITION FOR LIGHT GUIDE PLATE WITH IMPROVED HUMIDITY RESISTANCE AND LIGHT STABILATY AND THE LIGHT GUIDE PLATE MANUFACTURED BY THE RESIN COMPOSITION

摘要

The present invention is made using a thermoplastic resin composition and the resin composition for moisture resistance and light resistance is excellent in the light guide plate that relates to a light guide plate, a methyl methacrylate-styrene copolymer, benzotriazole ultraviolet absorber, and comprising a hindered amine light stabilizer, wherein the methyl methacrylate-styrene content of the styrene copolymer is a methyl methacrylate acrylate-styrene copolymer will be based on 100 parts by weight of a thermoplastic resin composition for light guide plate, characterized in that 50 to 80 parts by weight. According to the present invention, the optical properties and the light resistance is good and less bending amount by the water, when applied to a resin composition for light guide plate, while maintaining excellent optical characteristics to provide a light guide plate that is the dimensional changes that occur due to a warp or chlorosis can.
