Photocurable formulations containing trifunctional thiol, trifunctional ene, and antibacterial allylimidazolium salts have been employed for transparent antibacterial coatings. The antibacterial component 1-allyl-3-dodecylimidazolium salt (ADIm) is prepared and chemically attached to polymer networks using a one-step thiol-ene photocuring reaction. Ultra-small (USANS) and small angle neutron scattering (SANS) measurements show that the photocured polymers are loosely networked three-dimensional structures with a mass fractal of approximately 2.7 ± 0.2. The minimum inhibitory concentration (MIC) for the ADIm was determined to be 500 μg/ml and 15.63 μg/ml for Escherichia coli (Gram negative) and Staphylococcus aureus (Gram positive) bacteria, respectively. Coating formulations containing 10 mol% of the antibacterial ADIm photocured on glass substrates showed strong antibacterial activity against environmental bacteria such as E. coli and/or S. aureus.

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.
