Abstract

PROBLEM TO BE SOLVED: To prevent the fogging of a plastic lens surface by the condensed water of moisture and/or water drops by providing this plastic lens surface with a surface layer contg. transparent photocatalytic titanium oxide particles. SOLUTION: The layer contg. photocatalysts is formed on the surface of a base material. The plastic lens surface is made highly hydrophilic according to the photoexcitation of the photocatalysts by having such surface structure. As a result, even if the moisture of the atmosphere condenses and adheres to the plastic lens surface, the condensed moisture does not grow to the form of water drops and turns to the form of a uniform water film. The fogging of the plastic surface by the condensed water of moisture and/or the water drops is prevented. When the surface layer consists of the photocatalysts alone, the photocatalysts are preferably an oxide. The oxide exhibits hydrophilicity in the state that the contaminants in the environment are not adsorbed and, therefore, the oxide is liable to exhibit the hydrophilicity and is capable of forming the uniform water film by expelling these contaminants by the photoexcitation and forming the absorbed water layer. The contaminants are expelled and the water films are formed by the effect of the photocatalytic titanium oxide incorporated into the surface layer exclusive of the inorg. oxide.

It is also often experienced that the lenses of eyeglasses and goggles are exposed to rain and splashes, and discrete droplets of water adhere to the surface, causing their surface to wrinkle, blur, become mottled, cloudy, or lose visibility. It Generally, the surface of an article is fogged because when the surface is placed at a temperature below the dew point of the atmosphere, moisture in the atmosphere condenses and condenses on the surface. If the condensed water droplets are sufficiently fine and their diameter is about ½ of the wavelength of visible light, the water droplets scatter light, the lens becomes apparently opaque, and the visibility is lost. If moisture condensation proceeds further and fine condensed water droplets coalesce with each other to grow into larger discrete water droplets, the surface will be shaded due to refraction of light at the water droplet-surface interface and the water-air interface. Blurred, mottled, or cloudy,
Visibility is lost. As used herein, the term "anti-fog" broadly refers to a technique for preventing optical hindrance due to such fogging, growth of condensed water droplets, and adhesion of water droplets.

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.

By providing a surface layer containing a photocatalyst, in response to photoexcitation of the photocatalyst, the surface of the surface layer exhibits hydrophilicity, the condensed water and / or water droplets of the attached moisture spread evenly on the surface of the layer, Moisture condensate and / or water drops will prevent fogging or overhang.

By containing silica, the surface is likely to exhibit a high degree of hydrophilicity near a water wetting angle of 0 °, and the hydrophilicity retention when held in a dark place is improved. The reason seems to be related to the ability of silica to store water in its structure.

By containing a super strong acid, the surface is likely to exhibit a high degree of hydrophilicity close to a water wetting angle of 0 °, and at the same time, the hydrophilicity maintaining property when kept in a dark place is improved. The reason is that when the surface layer contains a super strong acid, the polarity of the surface is extremely large irrespective of the presence or absence of light, so that water molecules, which are polar molecules, are selectively adsorbed over hydrophobic molecules. Easy to make. Therefore, a stable physically adsorbed water layer is easily formed, and even if the layer is kept in a dark place, the hydrophilicity of the surface can be maintained at a high level for a considerably long period.

A layer containing a photocatalyst is formed on the surface of the base material on the surface of the antifogging plastic lens in the present invention, as shown in FIG. 1 or 2. By taking such a surface structure, the plastic lens surface is highly hydrophilized in response to photoexcitation of the photocatalyst. As a result, even if the moisture in the atmosphere condenses and adheres, it does not grow in the form of water droplets but becomes a uniform water film.
Or, it is prevented from being clouded or covered by water drops.

が形成できる。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 is hydrophilic when the pollutants in the environment are not adsorbed, the photocatalytic titanium oxide mixed into the surface layer other than the inorganic oxide removes the contaminants by the photoexciting action, and the adsorbed water layer Is formed, a uniform water film can be formed.
