Abstract
A transparent laminate comprises an optically clear, cured coating layer including abrasion-resistant nanoparticles, and one or more monomers and/or one or more oligomers that are reacted in the presence of an ultraviolet light photoinitiator. The coating layer also contains a surface portion rich in hydrophilic surfactant so that the coating layer when residing on a transparent substrate forms a laminate having good abrasion resistant properties as well as good anti-fog properties.
