ANTIBACTERIAL COATING FILM, ARTICLE PROVIDED WITH SAME, METHOD FOR FORMING ANTIBACTERIAL COATING FILM, AND COATING LIQUID FOR FORMING ANTIBACTERIAL COATING FILM

摘要

An antibacterial coating film (10) which contains: at least one kind of metal particles (3) that are selected from the group consisting of bulk metal particles having an average particle diameter of from 0.3 μm to 25 μm (inclusive) and flake-like metal particles having a thickness of from 0.01 μm to 5 μm (inclusive) and an aspect ratio of from 5 to 200 (inclusive); and a flake-like silica (2) having a thickness of from 0.0005 μm to 0.5 μm (inclusive) and an aspect ratio of from 10 to 5,000 (inclusive). This antibacterial coating film (10) is characterized in that: the metal particles (3) and the flake-like silica (2) are present in an amount of 50% by mass or more in total relative to the antibacterial coating film (10); the metal particles (3) are present in an amount of from 2% by mass to 50% by mass (inclusive) relative to the flake-like silica (2); and the metal particles (3) are buried in a laminate of the flake-like silica (2).
