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