Abstract
A polyester resin and a coating composition containing the polyester resin are disclosed. The polyester resin includes a repeating unit obtained by copolymerizing (a) a divalent acid component and (b) a diol component containing (b-1) an isosorbide and (b-2) a cycloaliphatic diol, and has excellent heat resistance and solubility in a solvent. The cycloaliphatic diol may be one or more diol derivatives of a tricycle Calkane. A coating formed from a coating composition containing the polyester shows excellent heat resistance, hardness, chemical resistance, pollution resistance, and hydrolysis resistance.
