Abstract
This invention relates to film composites with a single coating of hard coat material which have a significant improved adhesion together with improved weather resistance while also increasing resistance to abrasion and cracking. In one embodiment, this film composite is comprised of a transparent base sheet having on one side thereof a weather resistant hard coat comprised of: at least one multifunctional acrylate monomer or oligomer; a dual-curable resin comprising an aliphatic urethane acrylate resin having isocyanate functional groups and an aliphatic urethane acrylate having hydroxyl functional groups; an ultraviolet (UV) stabilizer; and a photoinitiator.
