    Abstract: A polymer and coating compositions containing the polymer are provided that are useful in coating applications such as, for example, food or beverage packaging coatings. The polymer preferably includes a polyester backbone and at least one deblockable isocyanate group attached to the backbone. In one embodiment, the polymer includes a polyester-carbamate backbone, one or more pendant deblockable isocyanate groups, and one or more terminal or pendant isocyanate-reactive groups. The deblockable isocyanate groups may be provided, for example, through use of a partially blocked polyisocyanate.
