OPTICAL DIFFUSIVE RESIN COMPOSITIONS AND OPTICAL DIFFUSIVE MOLDINGS
First Claim
1. Optical diffusive resin compositions comprising 100 mass parts of a thermoplastic polymer material and 0.1-10 mass parts of organisilicone fine particles, said organosilicone fine particles being each a particle having a hollow hemispherical shape as a whole, having a cross-sectional shape with an inner minor arc, an outer minor arc which covers said inner minor arc and ridge lines connecting ends of said inner minor arc and said outer minor arc, the average width between the end points of said inner minor arc being 0.01-9.5 μ
- m, the average width between the end points of said outer minor arc being 0.05-10 μ
m, and the average of the height of said outer minor arc being 0.015-9 μ
m, wherein the averages are values obtained from arbitrarily selected 100 of said organosilicone fine particles in a scanning electron microscope image thereof.

Abstract
Optical diffusive resin compositions are presented, capable of yielding optical diffusive moldings that are superior not only in rigidity and dimensional stability but also in heat resistance, optical transmissivity and optical diffusivity, as well as optical diffusive moldings molded by using them. Such optical diffusive resin compositions contain for 100 mass parts of a thermoplastic polymer material 0.1-10 mass parts of organosilicone fine particles of a specific kind comprising polysiloxane cross-linking structures, each particle having a hollow hemispherical shape as a whole, having a cross-sectional shape with an inner minor arc, an outer minor arc which covers it and ridge lines connecting their ends.
