ものである。2. Description of the Related Art As a coating composition to which a photocatalyst has been added, there is known a coating composition disclosed in Japanese Patent Application Laid-Open No. 10-101374. In this prior art, a colloid of alumina and fine particles of anatase-type titanium oxide are dispersed in an alkoxide solution of silica, and this solution is applied to a substrate.
By baking at 00 to 700 ° C, an antifogging film is formed.
【０００３】上記の被膜はアナターゼ型酸化チタンの光
触媒活性に由来する親水性と、もともとアルミナが有し
ている親水性によって防曇効果を発揮するものである。The above-mentioned coating exhibits an antifogging effect due to the hydrophilicity derived from the photocatalytic activity of anatase type titanium oxide and the hydrophilicity inherent to alumina.
【０００４】[0004]
【発明が解決しようとする課題】上記のTiO2-Al2O3-SiO
2系の被膜を、塗装面のような光沢のある基材表面に形
成すると、親水性（防曇性）は得られるのであるが、光
沢が失われるとういう不利がある。The above-mentioned TiO2-Al2O3-SiO
When a two-layer coating is formed on a glossy substrate surface such as a painted surface, hydrophilicity (anti-fog property) can be obtained, but there is a disadvantage that the gloss is lost.

きな材料を添加すると、親水性が低下してしまう。一般
に親水性を発揮する材料は屈折率が低いため親水性を高
める材料を多く添加すると今度は光沢が悪くなってしま
う。[0005] If the proportion of titanium oxide is increased in order to restore gloss, the surface of the substrate is degraded by a photocatalytic decomposition reaction at the interface with the substrate, and there is a problem in durability. Also, to increase the gloss, it is sufficient to add a material with a large refractive index,
If a material having no photocatalytic activity and a large refractive index is added instead of titanium oxide, hydrophilicity will be reduced. In general, a material exhibiting hydrophilicity has a low refractive index, so that if a large amount of a material enhancing hydrophilicity is added, the gloss will deteriorate.

ない。As described above, in a composition containing a conventional photocatalyst as a clear coat to be applied to a surface requiring gloss, such as an automobile body surface, the gloss of the substrate surface is maintained. However, there has not been provided any one having hydrophilicity (self-purifying function) and excellent durability.

しくなる。The amount of solvent in the composition according to the invention is
The concentration of the total amount of the above photocatalyst particles, hydrophilic inorganic fine particles, silica or / and silica precursor, and cerium oxide (hereinafter, may be referred to as “solid content concentration”) is 0.01 to 5 in the composition. % By weight or less. If the solid content exceeds 5% by weight, the surface to which the composition is applied may have a cloudy appearance or have interference fringes, which is not desirable. A more preferred upper limit is 3% by weight. The solid content is 0.01% by weight.
If it is less than this, there is a possibility that a sufficient hydrophilic surface cannot be efficiently formed. A more preferred lower limit is 0.05% by weight, most preferably 0.1% by weight. In the composition according to the present invention, the amount of the solvent is determined so that the solid concentration is in the above range. The coating composition according to the present invention may include a tin tetraalkoxide. The addition of the tin tetraalkoxide, when the composition according to the invention is applied to a substrate, can accelerate the curing speed and consequently increase the initial water resistance. The tin tetraalkoxide is cured by hydrolysis and polycondensation, but the final form in the film is kept in an amorphous state so as not to have photocatalytic activity. Tin tetraalkoxide is represented by the general formula Sn (OR) 4 (wherein R represents a hydrocarbon residue having 1 to 5 carbon atoms). Specific examples of tin tetraalkoxides include, for example, tetramethoxytin, tetraethoxytin, tetra-n-propoxytin, tetra-i-propoxytin, tetra-n-butoxytin, tetra-sec-butoxytin, tetra-t- Butoxytin and the like can be mentioned. Of these tin tetraalkoxides, tetramethoxytin and tetraethoxytin are particularly preferred. These tin tetraalkoxides can be used alone or in combination of two or more. In the present invention, the content of tin tetraalkoxide is preferably 0.05 to 2 parts by weight of tin tetraalkoxide when the silica precursor is 1 part by weight in terms of silica. If the concentration of tin tetraalkoxide is less than 0.05 parts by weight, the effect of accelerating the curing rate cannot be expected. On the other hand, if the amount exceeds 2 parts by weight, the curing speed is too fast, and it is difficult to form a uniform coating.

At this time, if alcohol derived from the composition according to the present invention remains on the surface, the surface may not be sufficiently hydrophilized until hydrophilization by the photocatalyst is obtained. Thus, the addition of a surfactant is preferable because the surface can be sufficiently hydrophilized even immediately after the application of the composition. Furthermore, the addition of a surfactant also has the advantage that the composition according to the invention can be applied homogeneously to the surface of the component.

It is more preferable that the thickness be 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. Furthermore,
When the film thickness is reduced, the wear resistance of the surface layer is improved.
