摘要:
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:>>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.
摘要:
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.
