Abstract: 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 mono-cyclic group having five ring members or less, a polycyclic group, or both, preferably in a backbone of the polyester polymer.

Abstract: Disclosed are Bisphenol A (BPA), Bisphenol F, Bisphenol A diglycidyl ether (BADGE), and Bisphenol F diglycidyl ether (BFDGE)-free coating compositions for metal substrates including an under-coat composition containing a polyester (co)polymer, and an under-coat cross-linker; and an over-coat composition containing a poly(vinyl chloride) (co)polymer dispersed in a substantially nonaqueous carrier liquid, an over-coat cross-linker, and a functional (meth)acrylic (co)polymer. Also provided is a method of coating a metal substrate using the BPA, BPF, BADGE and BFDGE-free coating system to produce a hardened protective coating useful in fabricating metal storage containers. The coated substrate is particularly useful in fabricating multi-part foodstuffs storage containers with “easy-open” end closures.
