A coated article is disclosed that includes a metal substrate and a coating composition disposed on at least a portion of the metal substrate. The coating can be formed from a composition that includes an acrylic copolymer, which is preferably the reaction product of ethylenically unsaturated monomers and a functional monomer. The functional monomer can be the reaction product of a multifunctional isocyanate and an ethylenically unsaturated nucleophilic monomer. The functional monomer preferably includes a blocked isocyanate group. The articles can be useful for packaging foods and beverages. L'invention porte sur un article revêtu qui comprend un substrat métallique et une composition de revêtement disposée sur au moins une partie du substrat métallique. Le revêtement peut être formé à partir d'une composition qui comprend un copolymère acrylique, qui est de préférence le produit de réaction de monomères à insaturation éthylénique et d'un monomère fonctionnel. Le monomère fonctionnel peut être le produit de réaction d'un isocyanate multifonctionnel et d'un monomère nucléophile à insaturation éthylénique. Le monomère fonctionnel comprend de préférence un groupe isocyanate bloqué. Les articles peuvent être utiles pour emballer des aliments et des boissons.
