Abstract: A bio-based polycarbonate ester resin is environment friendly by not containing a bisphenol, and exhibits excellent heat resistance, transparency, strength, hardness, dimensional stability and chemical resistance. Thus, the bio-based polycarbonate ester resin is suitable for use in an eyeglass frame. In addition, various colors may be painted and coated on during post-processing, a separate additive is not required during a molding process, and processing is undergone at a temperature lower than that for conventional plastic materials for an eyeglass frame, and thus manufacturing costs may be reduced.
