1. An enamine functional polymer comprising the reaction product of an acetoacetoxy functionalized polymer and an amine selected from the group consisting of ammonia, a primary amine, and a secondary amine, wherein said acetoacetoxy polymer comprises the free-radical polymerization product of:

  • a monomer of formula (I);

    ##STR7## where R1 and R2 are both a --C(O)R3 group;

    R3, which can be the same or different, is selected from the group consisting of a C1 -C24 alkyl group, an aromatic or heteroaromatic group, a C3 -C8 cycloalkyl or C2 -C7 heterocyclic group, and a --CH2 --C(O)--R4 group;

    R4 is a C1 -C6 alkyl group;

    wherein at least one of R1 and R2 is an acetoacetoxy group;

    and an ethylenically unsaturated monomer.
