Abstract
The present invention relates to a polyester resin with excellent solubility in generic solvents, especially with excellent solubility at a temperature of 0° C. or lower. According to the present invention, by using the polyester resin with excellent solubility in generic solvents, solubility at a lower temperature, especially the solubility at a temperature of 0° C. or lower, is enhanced, making it easier to prepare paints, coatings and the like. The polyester resin related to the present invention contains 0.05 to 0.5 mol of an isosorbide-derived structural unit and 0.015 to 0.4 mol of a trihydric or higher alcohol-derived structural unit relative to 1 mol of a polycarboxylic acid-derived structural unit.
