Abstract

See full text

Hard coating compositions and articles coated with said hard coating compositions are described. The coating compositions include at least a first layer as a hard coating to which is adhered a sputtered silicon containing layer, wherein the hard coating is formed with an unhydrolyzed alkoxysilane monomer cured cationically to increase a total amount of hydroxyl functional groups available in the first layer upon curing. The increased hydroxyl functional groups in the hard coating interact with the sputtered silicon containing layer and promote adherence between the hard coating and the sputtered silicon containing layer.
