Abstract
To provide a crosslinked polyester resin by using environmentally friendly and low-cost raw materials while reducing the content of a bisphenol A-derived component. [Subject Matter] [Solutions] To provide a polyester resin containing a trivalent or higher acid-derived component and a bisphenol A-alkylene oxide adduct-derived component. In such a polyester resin, the bisphenol A-alkylene oxide adduct-derived component is contained at 0.01˜0.35 mol relative to 1 mol of all the acid-derived components, and the ratio of acid value (mg KOH/g) to hydroxyl value (mg KOH/g) is set to be 1:3˜1:26.
