落とすことができない。BACKGROUND OF THE INVENTION Hard surfaces that are directly exposed to the outdoors, such as car bodies, glass, metal surfaces, or the exterior walls of certain buildings, are not only those inorganic materials such as dust and salts floating in the atmosphere, but also those of recent times. Under the influence of organic carbon derived from exhaust gas and rain dew containing them, the initial brightness is lost in proportion to the exposure time. Conventionally, a hard surface such as a car body has been treated by applying a wax treatment or a fluorine coating which also serves to protect the paint to impart water repellency. However, such a wax treatment promotes the adhesion of the organic dirt derived from the exhaust gas typified by the carbon, and the aggregation of the dirt due to the drying of the polka dots occurs. Such dirt cannot be easily removed.

使用するには課題が残る。The technology using titanium oxide has a high antifouling effect by a photocatalytic reaction, but titanium oxide itself is very expensive. In addition, it is necessary to first perform a base coat treatment to protect the coating before performing the titanium oxide treatment in order to prevent the coating itself on the hard surface from being damaged by active species generated by the photocatalytic reaction of titanium oxide In addition, titanium oxide having poor dispersibility must be uniformly dispersed on the base coat. As described above, the antifouling treatment using titanium oxide requires a high level of technology, and therefore lacks versatility, and there remains a problem in using it for home use.
