Abstract
A method for preparing a coated article which includes: (a) providing a substrate; (b) applying a photo-polymerizable coating composition to at least a portion of the substrate, where the photo-polymerizable coating composition includes a photo-polymerizable anisotropic material, and a photoinitiator; (c) ordering the anisotropic material present in the photo-polymerizable coating composition; and (d) exposing the ordered photo-polymerizable coating composition of (c) to a light emitting diode light source having a peak emission wavelength ranging from 385 to 460 nanometers to cure the photo-polymerizable coating composition is provided herein. The photoinitiator is capable of activation at the emission wavelength of the light emitting diode light source.
