Abstract

Provided is an antibacterial liquid with excellent temporal stability in which caking due to sedimentation of solid components does not occur and with which a film capable of stably maintaining antibacterial properties can be formed, in a case of being formed into a film. Also provided are an antibacterial film formed using the antibacterial liquid, and a spray and a cloth including the antibacterial liquid. The antibacterial liquid includes an antibacterial microparticle, a binder, and a solvent, in which the antibacterial microparticle contains a silver-supporting inorganic oxide, the binder includes at least one compound having a siloxane bond, the solvent includes an alcohol and water, the concentration of solid contents is less than 5% by mass with respect to the total mass of the antibacterial liquid, and the content of the compound having a siloxane bond is 60% by mass or more with respect to the total solid content of the antibacterial liquid.

First claim

What is claimed is:

1 . An antibacterial liquid comprising: an antibacterial microparticle; a binder; and a solvent,
wherein the antibacterial microparticle contains a silver-supporting inorganic oxide, the binder includes at least one compound having a siloxane bond, the solvent includes an alcohol and water, the concentration of solid contents is less than 5% by mass with respect to the total mass of the antibacterial liquid, and the content of the compound having a siloxane bond is 60% by mass or more with respect to the total solid content of the antibacterial liquid.

2 . The antibacterial liquid according to claim 1 , wherein the average particle size of the silver-supporting inorganic oxide is 0.05 μm or more and less than 1.0 μm.

3 . The antibacterial liquid according to claim 1 , wherein the silver-supporting inorganic oxide is silver-supporting glass.

4 . An antibacterial film formed using the antibacterial liquid according to claim 1 .

5 . The antibacterial film according to claim 4 , which is not removable by a solution having a pH of 11 or lower.

6 . A spray comprising the antibacterial liquid according to claim 1 .

7 . A cloth comprising the antibacterial liquid according to claim 1 .

8 . The antibacterial liquid according to claim 2 , wherein the silver-supporting inorganic oxide is silver-supporting glass.

9 . An antibacterial film formed using the antibacterial liquid according to claim 2 .

10 . An antibacterial film formed using the antibacterial liquid according to claim 3 .

11 . A spray comprising the antibacterial liquid according to claim 2 .

12 . A spray comprising the antibacterial liquid according to claim 3 .

13 . A cloth comprising the antibacterial liquid according to claim 2 .

14 . A cloth comprising the antibacterial liquid according to claim 3 .
