PROBLEM TO BE SOLVED: To provide a light-diffusing plate which is excellent in heat resistance and shows a low water absorption and a high hardness. SOLUTION: A resin composition for a light-diffusing plate is obtained by dispersing 0.1-2.0 pts. partially crosslinked siloxane polymer particles, acrylic polymer particles or calcium carbonate in 100 pts. copolymer resin which has a weight average molecular weight of 80,000-300,000 and comprises 5-40 wt.% methyl methacrylate unit, 5-55 wt.%α-methylstyrene unit and 20-90 wt.% styrene unit. The light-diffusing plate is obtained by molding the same. COPYRIGHT: (C)2007,JPO&INPIT
