To provide a water dispersible urethane (meth) acrylate capable of obtaining a coating film excellent in mechanical strength, flexibility, oil resistance, weather resistance, surface hardness, appearance and wear resistance. SOLUTION: (a) an organic isocyanate, (b) a polycarbonate diol, (c) a compound having a hydrophilic group neutralizable with an alkaline group and at least two isocyanate-reactive groups, and (d) a hydroxyl group-containing (meth). In the water-dispersible urethane (meth) acrylate of the reaction product of acrylate, the polycarbonate diol (b) is a polycarbonate diol having a terminal hydroxyl group, and has a repeating unit represented by the formula (B) or the formula (C).
