Abstract
Disclosed herein are visible light curable coating compositions that provide transparent and abrasion-resistant coatings when cured on a substrate. The coating compositions comprise a difunctional acrylate monomer, a multifunctional urethane acrylate, a mercapto modified polyester acrylate, an organic solvent, a sole photoinitiator that is activated in the visible range of the electromagnetic spectrum, and optionally, a colloidal silica component. This invention also relates to articles coated with the visible light curable coating compositions of the invention and processes for preparation of such coated polymeric substrates, such as processes for surface restoration of mounted parts, such as surface restoration of automotive headlamps.
