<p>The problem addressed by the present invention lies in providing a styrene-based resin composition for optical applications that has excellent long-term thermal stability, shows little change in color or transmittance, and has excellent colorless transparency, as well as a molded product and a light guide plate. The present invention provides a styrene-based resin composition for optical applications, which is characterized in being a styrene-based resin composition formed from (a) a styrene-based resin having a weight-average molecular weight of 150,000 to 700,000, (b) a phosphorus-based antioxidant having a specific structure, and (c) a hindered phenol-based antioxidant having a specific structure, wherein in terms of 100 mass% of styrene-based resin composition, the content of (b) is 0.03 to 0.40 mass% and the content of (c) is 0.02 to 0.30 mass%.</p> |
