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.

A process for preparing sulfonium-stabilized, water-compatible, radiation-curable vinyl ester compounds wherein epoxy compounds having on the average at least one pendant or terminal 1,2-epoxy group per molecule are reacted with a mercaptan and with an unsaturated monocarboxylic acid to form, on the average, vinyl ester compounds containing sulfide moieties after which said sulfide moieties are reacted with an alkylene oxide and a protonic acid to form sulfonium moieties of said vinyl ester compounds.
