Abstract: A thermosetting urethane resin composition having excellent self-healing properties, antifouling properties, and elongation, a film including a curable coating of the thermosetting urethane resin composition, and a product including the film are provided. The thermosetting urethane resin composition contains a main agent containing a urethane prepolymer and an organic solvent and a curing agent. The urethane prepolymer contains a composition containing a polyol, a polyisocyanate, and a chain extender and has a hydroxy group at an end. The polyol contains a polyol having no aromatic ring. The polyol having no aromatic ring contains liquid and solid polycarbonate polyols. The polyisocyanate contains a polyisocyanate having no aromatic ring. The chain extender contains a low molecular weight triol. The curing agent contains triisocyanate. The percentage of the total amount of the low molecular weight triol and the triisocyanate is 10 mass % or higher and 35 mass % or lower.
