Abstract
A scratch resistant film formed by altering a surface energy of at least a portion of a substrate and disposing a first layer of coating on the substrate. The first layer of coating comprises a plurality of functionalized monomers and a solvent. The substrate then may enter a transition zone to wet the first layer of coating, wherein wetting the first layer of coating comprises disposing the substrate in a transition zone subsequent to disposing the first layer of coating. The first layer of coating is cured, and a second layer of coating is disposed on the first layer of coating, wherein the second layer of coating has a lower surface energy than the first layer of coating. The substrate may then enter a transition zone and be subsequently cured. A scratch-resistant film is formed; this film may be transparent, translucent, opaque, or combinations thereof.
