Abstract: A food or beverage container having a body portion or an end portion that includes a metal substrate with a coating composition disposed thereon. The coating composition includes a water-dispersible acrylic linear block copolymer made by surfactant-free heterogeneous radical polymerization (“SFHRP”). The block copolymer imparts a desirable combination of flexibility and corrosion resistance to the coating composition, and the substantial absence of surfactants during polymerization contributes to other desirable properties including good blush resistance.
