Abstract:
An antibacterial imidazolium compound, a photocurable coating composition, and an antibacterial coating film includes a compound represented by Chemical Formula 1 shown below or derivatives thereof. In Chemical Formula 1, description of X−, R1 and, R2 is the same as in the detailed description of the invention. The antibacterial imidazolium compound has excellent antibiosis over various strains, and is included in a photocurable coating composition so as to provide an antibacterial coating film by a simple method. Also, in the antibacterial coating film, the antibacterial imidazolium compound is included as a monomer and chemically bonded to a polymer chain, and thus, antibacterial performance can be maintained for a long period of time.
