Abstract
A coating composition may include one or more radiation-curable resins having reactive groups in a hydrophilic region, a reactive surfactant comprising a reactive moiety; and a photoinitiator, wherein, upon the exposure of the photoinitiator to light energy, the one or more radiation-curable resins are cured to form a hydrophilic network with the reactive surfactant being bound to the network by binding of the reactive moiety of the surfactant to the reactive groups of the one or more radiation-curable resins. The cured coatings provide long lasting, washable, anti-fog properties.
