Abstract
Disclosed herein is an improved process for preparing color-plus-clear coatings, the improvement comprising high solids thermosetting coating compositions comprising hydroxy-functional polyepoxides and anhydrides as effective curing agents therefor. Films of these coating compositions are of remarkable appearance and are attended by remarkably low volatile organic content (VOC).
