・防藻剤が使用されている。2. Description of the Related Art There are roughly two types of methods for imparting antibacterial, antifungal and antialgal properties to articles made of metal, glass, ceramic materials and the like. One is a kneading method in which an antibacterial, antifungal and algatic agent is directly kneaded into the material. In the case of articles made of metal, glass, and ceramic, the molding temperature is high, so that antibacterial agents such as silver and copper are used. Inorganic antibacterial, antifungal and antialgal agents are used.

使用されている。[0003] The other is a coating method for forming a coating layer containing an antibacterial, antifungal and antialgal agent on the surface of an article.
For example, a paint in which an antibacterial, antifungal, and antialgal agent is dispersed in various solvents together with a resin vehicle is applied, or glaze is applied using a glaze obtained by adding an antibacterial, antifungal, or antialgal agent to a glaze component.
In the former case, both organic and inorganic antibacterial, antifungal and antialgal agents are used, and in the latter case, inorganic antibacterial, antifungal and antialgal agents are used.

Also, since the molding temperature of ceramic products is high, even if an inorganic antibacterial, antifungal, and antialgal agent with high heat resistance is used, it is difficult to exhibit antibacterial properties. Even so, there are problems such as the fact that the antibacterial, antifungal and antialgal agents exist deep inside the article and do not exert any effective action on bacteria attached to the surface, which is uneconomical. (See FIG. 1 (a)).

Coating layer binder (resin vehicle, glaze component)
Is worn out by abrasion etc. in a relatively short period of time, the surface properties (eg, color tone, physical properties, etc.) of articles are significantly changed by the formation of a coating layer, and antibacterial, antifungal, and antialgal agents are used as glaze components. When the added glaze is applied and baked, there is a problem that antibacterial, antifungal and antialgal properties are deteriorated due to the baking treatment at a high temperature of at least 800 ° C (Fig. 1).

When a coating layer (glaze layer, enamel layer, etc.) has been formed in advance, it is necessary to use either of the following. That is, when the heat treatment is performed at the above-mentioned temperature or more, the dimensional accuracy, strength, surface color tone, and the like of the article are adversely affected. Even when the temperature is lower than the above-mentioned temperature, it is necessary to avoid a temperature range in which the physical properties of the article deteriorate, for example, a temperature range of 400 to 800 ° C. for stainless steel. On the other hand, an appropriate heating temperature for preventing the performance of the antibacterial, antifungal and antialgal components from deteriorating depends on the type of the antibacterial, antifungal and antialgal components used, but is usually 800 ° C. or lower.

ることが判る。(Evaluation Results of Examples) In Table 1, in all the examples and all the bacteria, those subjected to the antibacterial, antifungal and antialgal treatments had the bacterial count reduced to 100 cfu / ml or less. On the other hand, on the surface of the untreated article as a comparative example not subjected to the antibacterial, antifungal and antialgal treatments, the number of bacteria was hardly reduced. In all the examples, antibacterial / antifungal / algae-free treatments were not observed for molds and algae. Molds and algae were observed on the surface of the untreated article as an example. Therefore, it was confirmed that the product of the present invention exhibited antibacterial, antifungal and antialgal properties. In addition, it was confirmed that the product surface treated with antibacterial, antifungal, and antialgae was also pickled (Examples 2 and 3), showing good antibacterial, antifungal, and antialgal properties. It was also confirmed that the fungicidal and anti-algae components diffused into the surface layer of the article. Also, from the results of Tables 1 and 2, it can be seen that Comparative Example 4 is inferior to Example 2 in antibacterial, antifungal and antialgal properties.
