A novel, self-crosslinkable polydiene-functionalized polydieneophile-functionalized epoxy-amine adduct is disclosed, which self-crosslinkable epoxy-amine adduct is cureable at elevated temperature. The polydiene-functionalized polydieneophile-functionalized epoxy-amine adduct is the reaction product of polyhydroxy functional epoxy-amine reactant with preferably approximately equal molar equivalent amounts of diene functional mono-isocyanate and dieneophile functional mono-isocyanate. The self-crosslinkable epoxy-amine adduct is useful in coating compositions and like applications and is especially useful in cathodic electrocoating compositions and processes.
