Low contrast anti-reflection articles with reduced scratch and fingerprint visibility
Last updated:
Abstract:
Embodiments of articles including a low-contrast anti-reflection coating are disclosed. The coated surface of such articles exhibits a reduced difference in reflectance between a pristine state and when a surface defect is present. In one or more embodiments, the coated surface of such articles exhibits a first average reflectance in the range from about 0.6% to about 6.0% in a pristine condition and a second average reflectance of about 8% or less after removal of a surface thickness of the anti-reflection coating. In other embodiments, the coated substrate exhibits a second average reflectance of about 10% or less, when the coated surface comprises a contaminant. In some embodiments, the coated substrate exhibits a first color coordinate (a*.sub.1, b*.sub.1) in a pristine condition and a second color coordinate (a*.sub.2, b*.sub.2) after the presence of a surface defect such that .DELTA.a*b* is about 6 or less.
