Disclosed is a system for maintaining a pretreatment bath containing a pretreatment comprising a Group IVB metal. The system comprises an aqueous reducing agent comprising a metal cation and a latent source of sulfate which, upon reaction with a contaminant in the pretreatment bath, forms a metal sulfate. The contaminant comprises a nitrite source. The metal sulfate salt has a pKsp of 4.5 to 11 at a temperature of 25&#xb0; C. Also disclosed is a method for maintaining a pretreatment bath containing a pretreatment composition comprising a Group IVB metal. The method comprises supplying the reducing agent to the pretreatment bath in an amount sufficient to reduce a pollution ratio of the pretreatment bath to less than 1:1. Also disclosed are substrates with a pretreatment bath maintained according to the system and method.

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.
