Title:
SELF-CLEANING AGENT
Document Type and Number:
Japanese Patent JP2023130423
Kind Code:
A
Abstract:
To provide a self-cleaning agent capable of decomposing dirt components under indoor light.SOLUTION: The present invention provides a self-cleaning agent characterized by containing a visible light-responsive photocatalyst. The visible light-responsive photocatalyst is preferably one in which a metal compound is supported on titanium oxide (a). The titanium oxide (a) preferably contains rutile-type titanium oxide (a1). The metal compound is preferably a divalent copper compound. According to the self-cleaning agent of the present invention, in embodiments of organic materials such as fibers and inorganic materials such as slate boards, dirt components can be decomposed under practical indoor light. Furthermore, by using a specific visible light-responsive photocatalyst as the visible light-responsive photocatalyst, a self-cleaning agent with even better antibacterial and antiviral properties can be obtained.SELECTED DRAWING: None
