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, ΔEθ that is less than 5, where ΔE=√{(a*−a*)+(b*−b*)}, and a*and b*are color values a* and b* values of the point measured from a first angle θ, and a second angle θ, where θand θare any two different viewing angles at least 5 degrees apart in a range from about 10° to about 60° relative to a normal vector of the reflective surface.
