RESIN COMPOSITION FOR LIGHT DIFFUSION

摘要

The present invention provides a thermoplastic resin composition satisfying Formula 1 and having excellent light diffusion. The thermoplastic resin composition comprises a matrix resin selected from polycarbonate, polystyrene, and a mixture thereof, and heterogeneous polyorganosilsesquioxane particles having different average particle sizes. The heterogeneous polyorganosilsesquioxane particles are a first polyorganosilsesquioxane particle having an average particle size of 5 to 20 μm and a second polyorganosilsesquioxane particle having an average particle size of 0.3 to 1.2 μm. Accordingly, light penetration and light diffusion are excellent, and a brightline shielding function may be remarkably improved. (In Formula1, each of POS1 and POS2 means an average particle size, and POS1- POS2 = 4.)
