Abstract
Abstract Resinous compositions which are the Michael adducts of primary and/or secondary amines and polymers containing alpha, beta-ethylenically unsaturated moieties in conjugation with carbonyl moieties are disclosed. The compositions are depositable on substrates to form films. The films are amenable to oxidative and aminoplast cures and cure with light color. The compositions are desirable for use in cationic electrodeposition.
