Abstract
Ungelled thermosetting products are produced by reacting an amine-aldehyde condensate, such as malamine-formaldehyde or urea-formaldehyde resin, with a polyfunctional material containing both hydroxyl and carboxyl groups. Preferred polyfunctional materials include di(hydroxyaryl) alkylidene carboxylic acids. Water-dispersed compositions in which the vehicle comprises such reaction products alone or in combination with other resins are applied by electrodeposition.
