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.
