LIGHT-DIFFUSIVE METHACRYLIC RESIN MULTI-LAYER SHEET

PROBLEM TO BE SOLVED: To provide a methacrylic resin sheet of a multi-layer structure which has a high-grade feel with depth of the light-diffusive layer through a transparent layer and excellent light-diffusive performance and light transmissivity. SOLUTION: The methacrylic resin multi-layer sheet is composed of the following three layers. The first layer has a total light transmissivity of 3-80%, a haze of ≥90% and a thickness of 2-10 mm. The second layer lies between the first and second layers and has a total light transmissivity of 30-90% which is higher than that of the first layer, a haze of ≥80% which is lower than that of the first layer and a thickness of 1-3 mm. The third layer has a total light transmissivity of ≥90%, a haze of ≤1% and a thickness of 1-10 mm. COPYRIGHT: (C)2008,JPO&INPIT
