Abstract
A color neutral absorbing film applied as a coating on a glass substrate. The film is an antimony/tin oxide alloy coating containing at least about five atomic percent antimony. The coating is suitable for use in anti-reflective coatings containing other metal oxides or mixed metal oxides to achieve a coated glass article having a visible light transmittance of 30% or greater and a reflectance of less than 5%.
