Abstract: Embodiments of this disclosure pertain to articles that exhibit scratch-resistance and improved optical properties. In some examples, the article exhibits a color shift of about 2 or less, when viewed at an incident illumination angle in the range from about 0 degrees to about 60 degrees from normal under an illuminant. In one or more embodiments, the articles include a substrate, and an optical film disposed on the substrate. The optical film includes a scratch-resistant layer and an optical interference layer. The optical interference layer may include one or more sub-layers that exhibit different refractive indices. In one example, the optical interference layer includes a first low refractive index sub-layer and a second a second high refractive index sub-layer. In some instances, the optical interference layer may include a third sub-layer.

In some embodiments, an article comprises: a substrate comprising a first major surface; and an optical coating disposed over the first major surface. The optical coating comprises: a second major surface; a thickness; and a first gradient portion. A refractive index of the optical coating varies along a thickness of the optical coating. The difference between the maximum refractive index of the first gradient portion and the minimum refractive index of the first gradient portion is 0.05 or greater. The absolute value of the slope of the refractive index of the first gradient portion is 0.1/nm or less everywhere along the thickness of the first gradient portion.

Abstract: Articles are described that may include substrates having a major surface, the major surface comprising a first portion and a second portion. A first direction that is normal to the first portion of the major surface may not be equal to a second direction that is normal to the second portion of the major surface. The angle between the first direction and the second direction may be at least 15 degrees. An optical coating may be disposed on at least the first portion and the second portion of the major surface. The optical coating may form an antireflective surface.
