Abstract
Curable, liquid coating compositions based on polyepoxides and polyacid curing agents are disclosed. The compositions also contain volatile components such as solvent or curing agents which release volatile components upon curing. Also present is a relatively long chain aliphatic monocarboxylic acid which is present to improve the appearance of the coatings. The compositions are useful as coating compositions particularly as clear coats in color-plus-clear automotive coatings.
