Abstract (en)

[origin: WO2005120154A2] Disclosed is a substrate with an abrasion-resistant and scratch-resistant coating that has a low index of refraction and comprises magnesium fluoride and at least one metal oxide or metalloid oxide. Said coating can be obtained by applying a coating composition containing magnesium fluoride or a precursor thereof and at least one metal oxide, metalloid oxide, or a precursor thereof onto a substrate and then subjecting the same to a thermal treatment. The inventive coating is suitable for optical layers particularly on translucent substrates. Examples of adequate uses include antireflective layers and packets of interference layer.
