PROBLEM TO BE SOLVED: To provide a methyl methacrylate resin composition excellent in durability without damaging inherent transparency. SOLUTION: The methyl methacrylate resin composition containing 2-(1- arylalkylidene)malonic esters of 0.0005-0.1 pts.wt. to the methyl methacrylate- based resin composition of 100 pts.wt. Further, a hindered amine compounds such as a compound having 2,2,6,6-tetraalkylpiperidine skeleton may be included for improving durability. |
