ABSTRACT:
Radiation curable coating compositions, and especially electron beam-curable coating compositions, are disclosed in which magnetizable particles are dispersed in a liquid vehicle comprising a polyethylenically unsaturated polyurethane oligomer which includes a polycarbonate diol, and from 5% to 50%, based on the total weight of unsaturated material, of a polyethylenically unsaturated isocyanurate, such as a triacrylate of tris(2-hydroxyethyl) isocyanurate.
