- 52 - Abstract of the Disclosure A novel composition of matter is provided, which comprises certain polydiene-functionalized epoxy-amine adduct and certain polydieneophile-functionalized polyisocyanate oligomer, which epoxy-amine adduct and polyisocyanate oligomer are co-reactive at elevated cure temperature. The polydiene-functionalized epoxy-amine adduct comprises the reaction product of certain polyhydroxy functional epoxy-amine reactant with diene-functional mono-isocyanate reactant. The polydieneophile-functionalized polyisocyanate oligomer comprises the reaction product of polyisocyanate reactant, preferably a triisocyanate, with approximately equal molar equivalent amount of monohydroxy dieneophile reactant or monoamino dieneophile reactant or like isocyanate-reactive dieneophile reactant. The crosslinkable composition of matter is useful in coating and other applications, especially cathodic electrocoating applications.
