| 摘要 |
The present invention relates to a heat resistant light diffusion blend composition, and more precisely, a heat resistant light diffusion blend composition which is composed of a substrate resin prepared by blending styrene-maleic anhydride copolymer resin and polymethylmethacrylate resin and a light-diffusing agent composed of acrylic organic particles with a mean diameter of 1~20 mum alone or together with silicon organic particles with a mean diameter of 0.5~20 mum. Therefore, the heat resistant light diffusion blend composition of the present invention not only has high diffusivity and brightness but also excellent heat resistance, dimensional stability and mechanical properties with a low water absorption rate, so that this composition can be effectively used as a light diffusion plate and also be applied to a backlight for LCDs, lighting apparatus, signboards or glass showcases.
