Abstract
A composition comprising a compound having latent primary amine functionality is described. The compound having latent amine functionality is obtained by reacting a cyclic anhydride with an amine compound having two primary amine groups and one secondary amine group. The latent amine compound is combined with a compound having a plurality of cyclic carbonate groups in a crosslinkable coating composition.
