  • Method for preparing optical articles with multi-layer antireflective coatings
    Patent number: 11352292
    Abstract: The present invention is directed to a method for preparing a coated optical article including providing a non-conductive substrate; forming a conductive coating layer over the substrate; electrodepositing a first electrodepositable coating composition over the conductive coating layer to form a first electrodeposited inorganic coating layer; and electrodepositing a second electrodepositable coating composition over the first electrodeposited coating layer to form a second electrodeposited inorganic coating layer thereover, thereby forming a multi-layer antireflective inorganic coating over the conductive coating layer. Each of the first electrodepositable coating composition and the second electrodepositable coating composition is different one from the other, and each includes a sol prepared from a composition of a metal oxide precursor and protic acid such that each coating composition is hydrolyzed. Coated optical articles are also provided.
