Abstract
Abstract Esters of glycidyl polyethers of saturated phenols are especially useful in coating compositions having a low organic solvent content. The esters are the reaction products of from about 0.5 to about 1.5 equivalents of a saturated monocarboxylic acid with each epoxy group in a diglycidyl polyether of phenols where the aromatic rings of the phenols are saturated.
