Abstract
Provided are polytriglyceride-AAG compositions, and corresponding coatings and coated articles. Also provided are methods for preparing the polytriglyceride-AAG compositions, and corresponding reagents including β-ketoimide compositions and triglyceride-AAG (acetoacetyl group) compositions. Coatings using the polytriglyceride-AAG compositions may be useful for, e.g., replacing bisphenol-A cross-linked coatings used in food and beverage containers, coating metal articles, and the like.
