## Abstract

To obtain light-diffusing polycarbonate resin compositions which show excellent light diffusing characteristics while maintaining the impact strength and other inherent properties of the matrix resin. Resin compositions in which certain light-diffusing fine particles are added and dispersed in 100 wt. parts polycarbonate resins.

## Claims

### Claim 1

A light-diffusing polycarbonate resin composition comprising from about 0.001 to about 10.00 wt. parts polymethyl silsesquioxane dispersed in 100 wt. parts polycarbonate resins.

### Claim 2 (depends on 1)

The light-diffusing polycarbonate resin compositions of claim 1 wherein the average polymethyl silsesquioxane particle size is, from about 0.1 to about 10 .mu.m.
