The diene functional blocked dieneophile functional aminoepoxy resin comprises the reaction product of diepoxide with amine functional diene chain extending reactant, amine functional blocked dieneophile chain extending reactant, optionally, monofunctional end-capping reactant such as mono-secondary amine functional diene and mono-secondary amine functional blocked dieneophile, and modifying agent comprising hydroxy functional secondary amine. Compositions comprising the aforesaid self-crosslinkable resin may further comprise crosslinking agent reactive with hydroxy functionality of the resin.Type: GrantFiled: December 10, 1984Date of Patent: October 28, 1986Assignee: Ford Motor CompanyInventor: S. Burhan A. Qaderi
