Disclosed is a hard coating composition for metal bases which is characterized by comprising a coating film-forming resin component containing a urethane (meth)acrylate which is obtained by reacting a polyisocyanate compound, a polyol and a (meth)acrylate monomer having a hydroxyl group. This hard coating composition for metal bases is further characterized in that the polyisocyanate compound is hydrogenated xylylenediisocyanate and/or hydrogenated dicyclohexylmethane diisocyanate.
