As a result, the deposits and/or contaminants adhered to the surface of the outdoor display board are flushed away by rain drops when the surface of the outdoor display board is exposed to the rainfall. The adhesion of the contaminants on the surface when the rain water contg. the contaminants flows down on the surface of the outdoor display board is prevented. Further, the washing of the surface of the outdoor display board with water is made easy. If the surface layer consists of the photocatalyst alone, the photocatalyst is preferably an oxide.

の期間持続する。SUMMARY OF THE INVENTION The present invention is based on the discovery that, in a member having a surface layer containing a photocatalyst formed thereon, when the photocatalyst is photoexcited, the surface of the member is highly hydrophilized. This phenomenon is considered to proceed by the following mechanism. That is, when the photocatalyst is irradiated with light having an energy larger than the energy gap between the valence band upper end and the conduction band lower end of the photocatalyst, the electrons in the valence band of the photocatalyst are excited to generate conduction electrons and holes. The action of either or both of them probably imparts polarity to the surface and collects polar components such as water and hydroxyl groups. Then, one or both of conduction electrons and holes and the above-mentioned polar component cooperate with each other to cut off a chemical bond between the surface and the contaminant chemically adsorbed on the surface, and to cause a chemical adsorbed water on the surface. Is adsorbed, and a physically adsorbed water layer is formed thereon. Further, once the surface of the member is highly hydrophilized, the hydrophilicity of the surface is maintained for a certain period even if the member is kept in a dark place.

As shown in FIG. 1 or FIG. 2, a layer containing a photocatalyst is formed on the surface of the substrate. By taking such a surface structure, the surface of the outdoor display panel is highly hydrophilized in response to photoexcitation of the photocatalyst. Thereby, the hydrophilicity of the surface becomes stronger than the lipophilicity. As a result, when the surface of the outdoor display board is exposed to rainfall, the adhered deposits and / or contaminants are washed away by raindrops. In addition, when rainwater containing contaminants flows down the surface of the outdoor display board, the contaminants are prevented from adhering to the surface. Further, it becomes easy to wash the surface of the outdoor display board with water.

る。In FIG. 1, when the surface layer is composed of only the photocatalyst, the photocatalyst is preferably an oxide.
By doing so, the oxide shows hydrophilicity in the state where the pollutants in the environment are not adsorbed, so that the pollutants are rejected by the photoexcitation action and the adsorbed water layer is formed, so that the oxides easily exhibit hydrophilicity. A uniform water film can be formed. In FIG. 2, M represents a metal element. Therefore, in the case of FIG. 2, the outermost surface is made of a general inorganic oxide. Again,
Since the oxide shows hydrophilicity in a state where the pollutant in the environment is not adsorbed, the pollutant is rejected by a photoexcitation effect of a photocatalyst mixed into the surface layer other than the inorganic oxide,
By forming the adsorbed water layer, a uniform water film can be formed.

い。The photocatalyst means an electron in the valence band when irradiated with light (excitation light) having an energy (that is, a short wavelength) larger than the energy gap between the conduction band and the valence band of the crystal. A substance that is excited (photoexcited) to generate conduction electrons and holes. For example, anatase-type titanium oxide, rutile-type titanium oxide, tin oxide, zinc oxide, dibismuth trioxide, tungsten trioxide, and oxide oxide. Diiron, strontium titanate and the like can be preferably used. Here, as the light source used for the photoexcitation of the photocatalyst, sunlight; a light source in the environment such as a street lamp or a night light; Here, as the electric lamp, a light source such as a fluorescent lamp, an incandescent lamp, a metal halide lamp, a mercury lamp, a xenon lamp can be preferably used. In order to make the surface of the base material highly hydrophilic by photoexcitation of the photocatalyst, the illuminance of the excitation light is 0.001 mW /

It is preferable that the thickness is less than or equal to μm. Then, white turbidity due to irregular reflection of light can be prevented, and the surface layer becomes substantially transparent. More preferably, the thickness of the surface layer containing the photocatalyst is 0.2 μm or less. Then, it is possible to prevent the surface layer from being colored by light interference. Also, the thinner the surface layer, the better its transparency.
Further, when the film thickness is reduced, the wear resistance of the surface layer is improved. The surface of the surface layer may be further provided with a wear-resistant or corrosion-resistant protective layer capable of being made hydrophilic and other functional films.

A platinum group metal such as h, Ir, Os can be added. The surface layer to which the metal is added can enhance the oxidation-reduction activity of the photocatalyst and improve the deodorizing and purifying action and the like. Further, when a solid superacid other than the photocatalyst is added, since the acidity of the solid superacid is improved by the addition of the platinum group metal, the hydrophilicity maintenance property is also improved and the formation of a water film of the adhered water is further promoted. Also, the hydrophilicity maintaining property is improved when the photocatalyst is not irradiated with the excitation light for a certain period of time.

Good. Then, the diffusion of the alkali network modifying ions from the base material to the surface layer during the firing is prevented, and the photocatalytic function is more effectively exhibited.

First, the production method in the case where the surface layer is composed of only the photocatalyst will be described by taking the case where the photocatalyst is anatase type titanium oxide as an example. In this case, there are roughly three methods. One method is a sol coating and firing method, the other method is an organic titanate method, and the other method is an electron beam evaporation method.
