Abstract
Sulfonium-stabilized, water-compatible, radiation-curable vinyl ester resins are prepared by the process of reacting an epoxy resin having on the average at least one vicinal epoxy group with a mercaptan and with an unsaturated monocarboxylic acid to form vinyl ester resins containing sulfide moieties which are then reacted with a protonic acid and an alkylene oxide. Compounds so prepared can be diluted with water and used as coatings.
