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.

Vinyl esters with high cross-linkage density

One-component thermosetting coating composition

A coating material crosslinkable by radiation comprising a) an olefinic unsaturated ester of an epoxy novolac resin, b) a binder formed by reaction of an epoxy compound having more than one epoxide group per molecule with at least one carboxylic acid in a molar ratio of epoxy groups per carboxyl group of 1:0.5 to 0.9 and subsequent reaction of the resulting reaction product with at least one unsaturated isocyanate ester formed by reaction of a compound with at least two isocyanate groups with a member of the group consisting of hydroxyl containing acrylic acid, methacrylic acid and cyanacrylic acid esters, c) at least one latent hardener, d) at least one photoinitiator e) 80-120% by weight of fillers and (f) additives, adjuvants and solvents and protective films formed with them.

Coating materials containing a reaction product of an epoxy novolak

Binder mixtures crosslinkable by radiation comprising as component A a product obtained by reaction of an epoxy compound with more than one epoxide group per molecule with at least one carboxylic acid in a molar ratio of epoxide groups to carboxyl groups of 1:0.5-0.9 and subsequent reaction of the reaction product with at least one unsaturated isocyanatocarbamate esters and as component B a product obtained by reaction of an epoxy compound with more than one epoxide group per molecule with at least one olefinic unsaturated carboxylic acid in a molar ratio of epoxide groups to carboxyl groups of 1:&gt;&gt;1 and subsequent reaction of the reaction product with at least one polybasic carboxylic acid or anhydride(s) thereof, components A and B being present in a weight ratio of 3:1 to 1:3 useful for the product of superior photo-resists and protective lacquers.
