The invention relates to corrosion inhibitors, and more specifically corrosion inhibitors for coating compositions. The invention provides for coating compositions that have improved corrosion properties, including reduced flash rust during the application of the coating composition to a metal surface, and even improved corrosion inhibition in the resulting dried coating. The invention also provides for methods of making and using the described the compositions and the corrosion inhibitors thereof. La présente invention concerne des inhibiteurs de corrosion, et plus particulièrement des inhibiteurs de corrosion destinés à des compositions de revêtement. L'invention concerne des compositions de revêtement qui présentent des propriétés anticorrosion améliorées, y compris une oxydation superficielle réduite durant l'application de la composition de revêtement sur une surface métallique, de même qu'une inhibition de corrosion améliorée dans le revêtement séché ainsi obtenu. L'invention concerne également des procédés de fabrication et d'utilisation des compositions décrites et de leurs inhibiteurs de corrosion.
