<P>PROBLEM TO BE SOLVED: To provide a composition which does not deteriorate the impact resistance of a polycarbonate resin, is little discolored and has a light-diffusing property. <P>SOLUTION: This light-diffusing polycarbonate resin composition is characterized by dispersing silicone rubber particles having a weight-average particle diameter of 0.5 to 10 μm in a polycarbonate resin. Preferably, the silicone rubber particles have methacryloyloxy groups on the surfaces and are contained in an amount of 0.01 to 10 pts. mass per 100 pts. mass of the polycarbonate resin. A method for producing the light-diffusing polycarbonate resin composition comprises melt-kneading the polycarbonate resin with the silicone rubber particles having a weight-average particle diameter of 0.5 to 10 μm. A light-diffusing sheet comprising the light-diffusing polycarbonate resin composition does not deteriorate impact resistance and is little discolored. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
