Abstract
Ungelled polyester oligomers which are formed from reacting polyols, 1,2-dicarboxylic acid anhydrides and polyepoxides are disclosed. The polyesters are useful as resinous binders in high solids coating compositions. The coating compositions can be applied by spraying and do not result in a tacky overspray common with many high solids coating compositions.
