PURPOSE:An electron beam-curable composition which can give a paint film excellent in surface property and uniformity, comprising a specified electron beam- curable compound and a metal (oxide) powder. CONSTITUTION:An electron beam-curable compound of a MW of 280-8,000 having an unsaturated group and an isocyanato group in the molecule, is obtained by a method such as a reaction of 1mol of a diisocyanate compound with about 0.15-2.85mol of a monoalcohol having a radical-polymerizable unsaturated group, or a reaction of 1mol of a trialcohol with about 1.5-3mol of a diisocyanate and about 0.15-2.85mol of a monoalcohol having a radical-polymerizable unsaturated group. 5-70wt% said compound is mixed with 95-30wt% metal (oxide) powder (e.g., titanium white or magnetic substance powder).
