<p>An electron beam-curable coating composition is disclosed in which magnetizable particles are dispersed in a liquid vehicle comprising at least one viscous nonpourable liquid to normally solid polyethylenically unsaturated compound having at least 2.5 repeating units held together by urethane linkages. The repeating units are polyether diol groups having a molecular weight in the range of 500 to 2500, and the polyethylenically unsaturated compound has an average of at least two ethylenically unsaturated groups per molecule and an average of one ethylenically unsaturated group per from 750 to 10,000 units of molecular weight. The compound is preferably used in a solution containing volatile organic solvent and a low molecular weight polyacrylate.</p> |
