Description of the Related Art In recent years, an antibacterial glaze composition in which an antibacterial agent is blended with a glaze composition has been proposed as disclosed in JP-A-6-340513, and this antibacterial glaze composition is used as a glaze for ceramics such as sanitary ware. A ceramic product is formed by glazing and firing the surface.

る。However, when a glaze is applied to ceramics, it is necessary to apply the glaze to a sufficient thickness, and the amount of the glaze used in the antibacterial glaze composition increases, and the amount of the antibacterial agent used increases. There is a problem that the product cost increases at most.
In other words, the antibacterial agent is extremely expensive in terms of cost, and there is a problem that as the use amount of the antibacterial agent increases, the product cost increases.

けが複雑になって生産性が悪くなるという問題がある。[0004] In order to reduce the amount of the antibacterial agent used, the glaze applied to the ceramic is divided into two layers, the lower first glaze layer is made a normal glaze free of the antibacterial agent, and the upper second layer is used. It is conceivable that the glaze layer is a layer containing an antibacterial agent and a thin layer. In this case, since a glaze containing another antibacterial agent is provided on the normal upper glaze, there is a problem that the color of the surface changes due to the difference between the color of the normal glaze and the glaze containing the antibacterial agent. If you try to make the first layer of the normal glaze and the second layer of the glaze containing the antibacterial agent the same color, the glaze containing the second layer of the antibacterial agent is the same as the color of the first layer of the normal glaze. There is a problem that a kind of color is required. In other words, the usual type of glaze and the glaze containing an antibacterial agent must be prepared for only the kind of color according to the kind of color of the product. For this reason, there is a problem that the productivity is deteriorated due to the manufacture and adjustment of the glaze, and that the use of the glaze is complicated and the productivity is deteriorated.

が白っぽくなる。BEST MODE FOR CARRYING OUT THE INVENTION The antibacterial glaze composition of the present invention comprises a transparent glaze composition and an inorganic antibacterial agent in which the amount of the antibacterial agent is 0.2 to 10% by weight based on the glaze composition. %, Preferably 1 to 5% by weight. The transparent glaze composition is a transparent glaze composition containing no opacifier or pigment. The usual glaze is made of an opacifying agent such as zirconium silicate to provide concealing properties so that the base material is not transparent, and is colored in an appropriate color with a pigment.However, the glaze composition having transparency uses the opacifying agent and the pigment. It is a glaze composition that cannot be added. Examples of the glaze composition having transparency include a glaze composition having a composition of 43% by weight of feldspar, 28% by weight of silica, 4% by weight of zinc white, 17% by weight of lime, 4% by weight of dolomite, and 4% by weight of clay. . However, the composition is not limited to the above, and any composition may be used as long as it is a glaze composition for ceramics and enamel from which opacifiers and pigments have been removed. There are various antibacterial agents disclosed in Japanese Patent No. 2524893. For example, inorganic antibacterial agents obtained by supporting silver on a metal phosphate double salt selected from calcium, zinc, aluminum and magnesium are preferable. Particularly, Silver Ace C435K manufactured by Taihei Chemical Industry Co., Ltd. is desirable. The addition amount of the antibacterial agent is set to 0.2% by weight to 10% by weight based on the solid content of the transparent glaze for the following reason. When the amount of the antibacterial agent is 0.2% by weight or less, the antibacterial property is small, and when the amount is 10% by weight or more, the coloring by the antibacterial agent is large and the transparency is low (the color of a product described later changes). In particular, when the amount of the antibacterial agent is 1% by weight to 5% by weight, there is no problem in both the antibacterial power and the transparency, and there is no problem in the antibacterial power and product color of the applied product. When the amount of the antibacterial agent is 5% by weight or more and 10% by weight or less, the color becomes slightly whitish.

As shown in FIG. 1, an ordinary color glaze 2 colored appropriately as shown in FIG. 1 is glazed as a first layer on the surface of the base material of a sanitary ware such as a bathtub or a ceramic 1 such as a tile. A layer of antibacterial transparent glaze 3 is glazed as a second layer and fired to form a ceramic product. There are many types of colors of the color glaze 2 (depending on the product, but generally there are more than 20 colors) corresponding to the color of the product.
As a result, the color glaze 2 can be seen through, so that only one type of the transparent glaze 3 can be used. The thickness of the first layer of the ordinary color glaze is not particularly limited as long as the required glaze state is obtained, and is, for example, about 800 μm. Antibacterial transparent glaze is responsible for quality such as chemical resistance, appearance such as gloss, and antibacterial power. Generally, gloss is increased by using a transparent glaze, but a mat type (matte type) may be used.

い。The glazing thickness of the transparent glaze 3 having antibacterial properties is 0.1 mm.
5 μm to 100 μm, preferably 0.5 μm to 25 μm. If the glaze thickness of the transparent glaze 3 is 0.5 μm or less, it is difficult to perform uniform glaze, and even if glaze is applied with a predetermined weight glaze, as shown in FIG. Glaze 2 cannot be covered, and the antibacterial activity varies. Therefore, when the transparent glaze 3 is glazed, it is necessary to completely cover the normal color glaze 2 as shown in FIG. The minimum required amount in this manner is 0.5 μm as a glazing thickness (a glazing amount of 3.2 g / m
2 ) about. When the glazed thickness is 25 μm or less (glaze amount 160 g / m 2 ) or less, it can be used without any color problem. However, a slight color shift occurs, but 100
It can be used up to about μm. The heat resistant temperature of the antibacterial agent is preferably around the melting temperature of the glaze (within ± 20 ° C).
