Summary:Vinyl esters of epoxides and unsaturated acid anhydrides are used as photo-curing prepolymers and as surface coating resins having good electrical properties, high adhesion on most substrates and good chemical resistance. However, there is a need for highly reactive vinyl esters having in addition to said good properties, also good temperature stability and better chemical resistance. A vinyl ester produced by reacting at least one epoxide compound with at least on carboxylic anhydride, containing ethylenically unsaturated groups, the epoxide groups being substantially substituted by two vinyl ester groups.
