ANTI-REFLECTIVE COATINGS AND ARTICLES AND METHODS OF FORMING THE SAME

Abstract:

Embodiments of a color-neutral anti-reflective coating and articles including the same are described. In one or more embodiments, a substrate includes a first major surface and an anti-reflective coating disposed on the first major surface of the substrate and having a reflective surface opposite the first major surface. In one or more embodiments, a point on the reflective surface has a single-surface reflectance under a D65 illuminant with an angular color variation, .DELTA.E.theta. that is less than 5, where .DELTA.E.sub..theta.= {(a*.sub..theta.1-a*.sub..theta.2).sup.2+(b*.sub..theta.1-b*.sub..theta.2- ).sup.2}, and a*.sub..theta.1 and b*.sub..theta.1 are any two different viewing angles at least 5 degrees apart in a range from about 10.degree. to about 60.degree. relative to a normal vector of the reflective surface.
