Abstract: Proposed are a coating resin composition for a flexible cover window and a flexible cover window formed using the same composition. The coating resin composition, includes, relative to the total weight thereof, 10 to 150 parts by weight of a urethane (meth)acrylate-based oligomer prepared by synthesizing an acrylic monomer containing a hydroxyl group with a urethane prepolymer synthesized from an ether-based polyol, diisocyanate, and polyoxyalkylene-based bisphenol ether, 1 to 60 parts by weight of a first photocurable acrylate-based monomer, 0.5 to 10 parts by weight of a second photocurable acrylate-based monomer, 0.5 to 10 parts by weight of an alkoxy silane coupling agent, 0.1 to 5 parts by weight of a siloxane additive, and to 20 parts by weight of a photopolymerization initiator.

Abstract: Disclosed is an antibacterial flexible cover window formed using an antibacterial coating composition containing antibacterial nanoparticles dispersed in a resin coating solution. In the antibacterial coating composition, 0.001 to 0.5 parts by weight of the antibacterial nanoparticles are dispersed in 100 parts by weight of the resin coating solution. The antibacterial flexible cover window includes an antibacterial layer that is formed by applying the antibacterial coating composition to a glass substrate. Therefore, the antibacterial flexible cover window exhibits a good and long-lasting antibacterial activity.
