PROBLEM TO BE SOLVED: To provide a door of a gate capable of obtaining high-degree photocatalytic decomposition activity even in the case that a coating film is formed on an enamel or clear coating surface in a thickness of above 2 μm in order to suppress the deterioration of the coating surface, and a coating solution for the door of the gate.SOLUTION: The door of the gate is constituted by providing a photocatalyst layer on the surface of a base material. The photocatalyst layer is obtained by coating the base material with a photocatalyst coating solution and subsequently drying the coated base material. The photocatalyst coating solution is composed of photocatalytic metal oxide particles, a curable silicone emulsion, a surfactant and water. The photocatalytic metal oxide particles are partially subjected to coating or modification treatment with a substance having a hydrophobic group, and the surfactant is a nonionic surfactant. |
