Abstract
Curable, high solids, liquid coating compositions are disclosed. The resinous binder comprises a copolymer of an alpha-olefin or cycloolefin and an olefinically unsaturated monoanhydride which may include a half-ester thereof. The coating compositions are useful as clear coats in color-plus-clear automotive coatings and have good humidity resistance and mar resistance.
