要求も高まってきている。As described above, many techniques relating to antifouling properties have been studied. However, the conventional technology mainly suppresses the generation of stains due to adhesion of water scales and faeces, and is insufficient for stains related to darkening caused by microorganisms and mold. In addition, recently, with the improvement of the living environment, more and more people are concerned about hygiene problems in addition to visible stains, and the demand for sterilization is increasing.

After repeating the flow and drying at a rate of 5 times / second, 0.5 g of oleic acid is dropped on the surface of the ceramic tile in the form of spots. The ceramic tile with the oleic acid dropped on it is kept at the bottom of the water tank so that oleic acid does not flow, and the water is gently filled with water so that the ceramic tile is not directly exposed to water. At that time, the ratio of the area where oleic acid was removed from the surface of the ceramic tile was determined, and evaluated in the following five steps. In addition, the average value of five model-contaminated plates was adopted as the percentage of stain removal. 5: The stain removal is 80% or more 4: The stain removal is 60% or more and less than 80% 3: The stain removal is 40% or more and less than 60% 2: The stain removal is 20% or more and less than 40% 1. : Stain removal is less than 20%.
