Abstract: PROBLEM TO BE SOLVED: To obtain a radiation-curable material as a coating material in an external region by adding specified amounts of a urethane acrylate and a photoinitiator to a radiation-curable compound. SOLUTION: A radical-copolymerizable ethylenically unsaturated compound is prepared as a radiation-curable compound. A urethane acrylate obtained by allowing a polyisocyanate and a hydroxyalkyl (meth)acrylate to react with a chain extender such as a diol, polyol, diamine, polyamine or dithiol is added to the radiation-curable compound by 10-100 wt.% of the total amount of the compound and a photoinitiator is also added by 0.1-10 wt.% based on 100 pts.wt. of the compound. The photoinitiator is phenylglyoxylic acid, its ester, its salt other than ammonium salt or a derivative of the compound.
