The latex polymer compositions of the present invention exhibit latent crosslinking properties. Latent crosslinking in the polymers takes advantage of the fast reaction that occurs between amine-reactive carbonyl groups in the polymer component and carbonyl-reactive amine nitrogens in the crosslinking component, but controls the rate of crosslinking by protonating the amines with a volatile acid. Once the latex is coated onto a substrate, the volatile acid evaporates and the carbonyl reactive amine nitrogens react with the amine reactive carbonyl groups to form a crosslinked coating.

La présente invention concerne des compositions polymères de latex présentant des propriétés de réticulation latente. Cette réticulation latente des polymères s'appuie sur la rapidité de la réaction entre les groupes carbonyles réactifs aux amines dans le constituant polymère, et les groupes d'azote amine réactifs aux groupes carbonyles dans le constituant de réticulation, et permet par ailleurs de réguler la vitesse de réticulation grâce à une protonation des amines effectuée à l'aide d'un acide volatil. Une fois le latex déposé sur un substrat, cet acide volatil s'évapore et les groupes d'azote amine réactifs aux groupes carbonyles réagissent avec les groupes carbonyles réactifs aux amines, de manière à former un revêtement réticulé.
