| titleOfInvention | High heat resistant acrylic copolymer and light diffuser composite sheet comprising thereof |
| abstract | The present invention relates to an acrylic copolymer having excellent heat resistance and optical properties and a composite sheet for a light diffuser including the same. In more detail, a high heat resistance acrylic copolymer is polymerized using a specific dispersion stabilizer and a monomer having a cyclic structure, and a composite sheet for a light diffusion plate is prepared using the same, thereby providing a composite sheet for a light diffusion plate having high heat resistance and high brightness. can do. The composite sheet for a light diffuser according to the present invention is prepared by including an acrylic copolymer having excellent heat resistance and low yellowness, and has excellent heat resistance and optical properties. Therefore, it can withstand the ever-increasing intensity and temperature of light sources, making it suitable for use in signboards, lighting fixtures, protective covers for car turn indicators, and direct backlight units for large displays that generate a lot of heat. |
