Abstract
The present invention provides a light diffusing thermoplastic resin composition comprising polycaprolactone, specific silicone rubber particles, and, when desired, a fluorescent brightening agent, an antioxidant and/or an ultraviolet light absorber. A light diffusion sheet can be obtained by molding the light diffusing thermoplastic resin composition, which has superior light diffusion properties, luminance, mechanical strength, thermal stability and light resistance.
Claims14
A light diffusing thermoplastic resin composition comprising 100 parts by weight of a resin component and 0.1 to 1.5 parts by weight of (C) silicone rubber particles having 0.5 μm to 10 μm of the average particle size, wherein the resin component consists of 0.1% to 7% by weight of (A) polycaprolactone and 93% to 99.9% by weight of (B) other transparent thermoplastic resins, and the (C) silicone rubber particles have a framework structure containing difunctional siloxane units and trifunctional siloxane units and have alkyl groups on the surface.
