Abstract of the Disclosure A crosslinkable composition of matter is provided, which comprises certain diene functional aminoepoxy resin and certain blocked dieneophile functional aminoepoxy resin, which two resins are co-reactive at elevated cure temperature. The diene functional aminoepoxy resin comprises the reaction product of diepoxide with amine functional diene chain extending reactant and, optionally, monofunctional end-capping reactant such as monohydroxy functional diene. The blocked dieneophile functional aminoepoxy resin comprises the reaction product of diepoxide with amine functional blocked dieneophile chain extending reactant and, optionally, monofunctional end-capping reactant such as monohydroxy functional blocked dieneophile. The composition may further comprise crosslinking agent reactive with hydroxy functionality of the resins. The crosslinkable composition of matter is useful in coating and other applications, especially solvent-based primer coating compositions and cathodic electrocoating compositions.
