Abstract
Scratch-resistant thermoplastic films are disclosed. The films include a scratch-resistant coating that is formed from an acrylated binder, a thermal initiator, and a melamine crosslinker. Of particular advantage, the coating can be formed on the film during an in-line process while the film is being formed. The melamine crosslinker not only causes the coating to crosslink but also improves the adhesion of the coating to the film layer. In one embodiment, the film layer is made from a polyester.
