    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: An antimicrobial solid material having a satisfactory antimicrobial activity for a long term against sewage in any form of circulating, static and flowing waters or contacting portions thereof and a utilizing method thereof are provided. An antimicrobial solid material as one embodiment of the present invention comprises both of an antimicrobial metal ion and an antimicrobial metal in a metal state. In general, it is believed that antimicrobial metal ions have a potent antimicrobial effect when they exist in a liquid to be treated with a certain concentration or more, but they are rapidly released and exhausted so that their antimicrobial effects cannot last long. On the other hand, it is believed that the antimicrobial metal in a metal state does not have a prompt effect, but exhibits a certain bacteriostatic and fungistatic effect continuously for a long term. Therefore, the antimicrobial solid material containing both of the antimicrobial metal ions and the antimicrobial metal in a metal state thereof has both of a potent initial antimicrobial activity and an enduring bacteriostatic and fungistatic activity.
