Summary:PROBLEM TO BE SOLVED: To provide a resin having excellent weather resistance and mechanical strength, and lowered deformation by moisture absorption and heat. SOLUTION: The resin has ≤1.0 yellowing index difference ΔYI between before and after accelerated exposure testing by JIS A 1415 (WS-A method of 600 hr continuous irradiation), ≥80 MPa flexural stress and ≥2.5 GPa flexural modulus by JIS K 7171, ≤1.6 mass% saturated water content and ≥1.2×10-6mm2/s water diffusion coefficient by JIS K 7209 and ≥90°C deflection temperature under load by JIS K 7191-2 (A method). The resin is preferably an acrylic resin satisfying these physical properties. The resin plate is composed of the resin. COPYRIGHT: (C)2007,JPO&INPIT
