(57) [Abstract] [PROBLEMS] To provide a decorative gold powder that can reduce the amount of coating required for decoration per unit area. SOLUTION: A surfactant is attached to the surface of flat gold powder particles. As the surfactant, a fluorine-based surfactant, a silicone-based surfactant, and a hydrocarbon-based surfactant can be used, and a fluorine-based surfactant having a molecular weight of 400-2000 is particularly preferable. |
