摘要： The present disclosure provides a coating composition useful as a coating on food cans, and particularly as interior white or gold food can coatings. The coating composition includes a polyester polymer preferably having a number average molecular weight (Mn) of less than 10,000, a glass transition temperature (Tg) of more than 60° C., and a hydroxyl value greater than 10 mg KOH/g resin. The polyester preferably includes one or more cyclic groups selected from a monocyclic group having five ring members or less, a polycyclic group, or both, preferably in a backbone of the polyester polymer.
