Abstract

Radiation cross-linkable binding agents formed by reacting first an epoxy component with more than one epoxy group per molecule with at least one carboxylic acid in a molar ratio 1 of epoxy group per 0.5 to 0.9 carboxyl groups and second reacting the said first reaction product with at least one unsaturated isocyanato carbamate ester prepared by reacting a compound containing at least two isocyanate groups with an ester of an acid selected from the group consisting of acrylic acid, methacrylic acid and cyanacrylic acid containing hydroxyl groups useful in electronics and electrotechnology for layering systems and cast resin materials.
