摘要： Disclosed is a photocatalyst that has excellent elasticity. In particular, the disclosed photocatalytic paint ensures the adhesiveness of a base and a photocatalytic layer, even when cracks form in the photocatalyst coating due to seasonal variations in the temperature of the coating surface, and considerably suppress the propagation and development of these cracks in both the surface and the base. The disclosed photocatalytic paint is provided with a base, a photocatalytic layer that includes the photocatalyst, and an intermediate layer that is provided so as to be interposed between the base and the photocatalytic layer and in contact with the underside of the photocatalytic layer. The intermediate layer includes a resin component, which has a silicone component and a flexible non-silicone component. The loss tangent of the intermediate layer at 25 °C, measured by a solid-matter viscoelasticity measuring device, is between 0.2 and 1.5. At least one spectral peak of the temperature change curve of the loss elasticity ratio, which is measured by a solid-matter viscoelasticity measuring device that is based on JIS K7244-4 for the intermediate layer, is greater than -80 °C and up to 30 °C.

摘要： Sanitary wares having a controlled surface are disclosed which are less likely to be stained or soiled and/or possess excellent gloss. The first sanitary ware comprises a sanitary ware body and a surface glaze layer provided on the sanitary ware body, wherein the surface glaze layer has a center line average roughness Ra of less than 0.07 µm. This sanitary ware is advantageous in that stains or soils are much less likely to be adhered to the surface thereof and, even when adhered to the surface thereof, can be removed by a weak water stream. The second sanitary ware comprises a sanitary ware body and a surface glaze layer provided on the sanitary ware body, wherein the surface glaze layer has a kurtosis Rku of less than 2.70. This sanitary ware advantageously possesses excellent surface gloss. The third sanitary ware comprises a sanitary ware body and a surface glaze layer provided on the sanitary ware body, wherein the surface of the surface glaze layer consists essentially of a vitreous component and is free from silica particles having a particle diameter of not less than 10 µm. This sanitary ware is advantageous in that stains or soils are less likely to be adhered to the surface thereof.

摘要： A photocatalytic functional material having an excellent photocatalytic activity even by a low temperature heat treatment and having a high mechanical strength of the surface. The photocatalytic functional material of the present invention comprises a surface layer (a photocatalytic functional layer) containing a photocatalyst, an electron- trapping metal and a photodegradation-resistant matrix. Though the major proportion of the photocatalyst (TiO2 particles, and the like) in the photocatalytic functional layer are covered with the photodegradation-resistant matrix (a thermosetting resin, and the like), the electron-trapping metal effectively traps the electrons generated by the photocatalytic reaction, retains positive holes and generates active oxygen species, so that the photocatalytic function such as deodorant and antimicrobial activities can be fully exhibited.

摘要： A composition is disclosed which can hydrophilify the surface of a member to impart an antifogging property to the surface of the member. The composition for hydrophilifying the surface of the member comprises at least (a) photocatalytic particles of a metallic oxide, (b) a precursor capable of forming a silicone resin film or a precursor capable of forming a silica film, and (c) a solvent, the total content of the photocatalytic particle and the solid matter of the precursor in the composition being 0.01 to 5% by weight. The hydrophilic property can be imparted simply by applying the composition onto a member and drying or heating the composition applied to the member. The resultant hydrophilic thin film is transparent and, hence, does not sacrifice the transparency and appearance of a member required to be transparent. Further, the surface of a member with the above composition applied thereto has such a property that water droplets adhered thereon can be immediately removed by vaporization and the surface is less likely to be soiled and, even when a contaminant is adhered thereon, can easily release the contaminant therefrom.

摘要： A COMPOSITION IS DISCLOSED WHICH CAN HYDROPHILIFY THE SURFACE OF A MEMBER TO IMPART AN ANTIFOGGING PROPERTY TO THE SURFACE OF THE MEMBER. THE COMPOSITION FOR HYDROPHILIFYING THE SURFACE OF THE MEMBER COMPRISES AT LEAST (A) PHOTOCATALYTIC PARTICLES OF A METALLIC OXIDE, (B) A PRECURSOR CAPABLE OF FORMING A SILICONE RESIN FILM OR A PRECURSOR CAPABLE OF FORMING A SILICA FILM, AND (C) A SOLVENT, THE TOTAL CONTENT OF THE PHOTOCATALYTIC PARTICLE AND THE SOLID MATTER OF THE PRECURSOR IN THE COMPOSITION BEING 0.01 TO 5BY WEIGHT. THE HYDROPHILIC PROPERTY CAN BE IMPARTED SIMPLY BY APPLYING THE COMPOSITION ONTO A MEMBER AND DRYING OR HEATING THE COMPOSITION APPLIED TO THE MEMBER. THE RESULTANT HYDROPHILIC THIN FILM IS TRANSPARENT AND, HENCE, DOES NOT SACRIFICE THE TRANSPARENCY AND APPEARANCE OF A MEMBER REQUIRED TO BE TRANSPARENT. FURTER, THE SURFACE OF A MEMBER WITH THE ABOVE COMPOSITION APPLIED THERETO HAS SUCH A PROPERTY THAT WATER DROPLETS ADHERED THEREON CAN BE IMMEDIATELY REMOVED BY VAPORIZATION AND THE SURFACE IS LESS LIKELY TO BE SOILED AND, EVEN WHEN A CONTAMINANT IS ADHERED THEREON, CAN EASILY RELEASE THE CONTAMINANT THEREFROM.
