Abstract

Disclosed is a polycarbonate resin a composition. The polycarbonate resin composition may simply and exactly improve appearance properties such as yellow index (Y.I), haze and the like, and thermal stability during a high-temperature process, and provide processability by reducing gas generation during molding, through provision of a relational formula of addition amounts of a hindered phenol-based compound and a phosphite-based compound which function as antioxidants when mixed with the polycarbonate resin.
