A coating composition comprising; a polyester material, and benzoguanamine or a derivative thereof, wherein the coating composition is substantially free of bisphenol A (BPA), bisphenol F (BPF), bisphenol A diglycidyl ether (BADGE) and bisphenol F diglycidyl ether (BFDGE), and wherein the coating composition, when cured, has a flexibility of at least 20mm as measured according to the draw and re-draw test method with processing in 1% salt (NaCl) solution in tap water at 130°C for 60 minutes and a scratch resistance of at least 700g as measured according to ISO Standard 1518-1:2011. L'invention concerne une composition de revêtement comprenant : un matériau de polyester et de la benzoguanamine ou un dérivé de celle-ci, la composition de revêtement étant pratiquement exempte de bisphénol A (BPA), de bisphénol F (BPF), d'éther diglycidylique de bisphénol A (BADGE) et d'éther diglycidylique de bisphénol F (BFDGE), et la composition de revêtement, lorsqu'elle est durcie, ayant une flexibilité d'au moins 20 mm, mesurée selon la méthode d'essai d'étirage et de ré-étirage avec traitement dans une solution de sel (NaCl) à 1 % dans l'eau du robinet à 130°C pendant 60 minutes, et une résistance à la rayure d'au moins 700g, mesurée selon la norme ISO 1518-1:2011.
