Abstract
A method of reducing optical fringing of a coated substrate is described. The method comprises providing a (e.g. light transmissive) substrate; providing a primer having an unmatched refractive index, and applying the primer to the substrate forming a primer layer having an optically significant thickness. The primer layer in combination with the substrate has a percent reflectance at a maximum at a wavelength of interest. Also described are articles comprising a substrate, a primer having an unmatched refractive index, a high refractive index layer, and optional low refractive index layer such as an antireflective film article.
