Process for making of glass articles with optical and easy-to-clean coatings

The present disclosure is directed to a process in which both an optical coating, for example an AR coating, and an ETC coating can be applied to a glass substrate article, in sequential steps of the optical coating first and the ETC coating second, using substantially the same procedure without exposing the article to the atmosphere at any time during the application of the optical coating and ETC coating. After post-treating the article to create strong chemical bonding between the ETC coating and the optical coating deposited on the substrate, and cross-linking between ETC molecules, the article has an average water contact angle of at least 70 degrees after 5,500 abrasion cycles using with #0 steel wool and 1 kg weight load on a 1 cm surface area.
