The invention relates to a dual-curing coating compound, which comprises containing hydroxyl macromolecular compounds provided with a hydroxyl value not lower than 50 milligram KOH per gram, compounds capable of generating cross linking reaction with the containing hydroxyl macromolecular compounds, and thinner, wherein, the compounds capable of generating the cross linking reaction with the containing hydroxyl macromolecular compounds are the compounds the molecules of which simultaneously contain isocyanate radical and polyradical. The dual-curing coating compound provided by the invention can obtain a paint film with good adhesive force, high flexibility and good scratch resistant performance after solidification and meet the requirements of a purse test and a vibration and wear resistant test when applied on the metal surface on one hand, and can effectively solve the problem in the prior art that the compatibility between thermocuring isocyanate and photo-curing polyurethane acrylic ester is poor so as to make the paint film smooth and neat on the other hand.
