Abstract
Abstract This invention relates to cationic electrodepositable coating compositions comprising an aminoalkyl monomer, a reaction product comprising a half-blocked diisocyanate and an ethylenically unsaturated hydroxyl-containing monomer. Such compositions can be formulated in such a manner as to provide suitable coatings which when cured have a pleasing appearance, good flexibility, hardness, and resistance to the action of water and chemicals.
