PROTECTIVE LAYER FOR COATED SUBSTRATE

摘要

The invention concerns a substrate bearing a coating and the method for making same. Said coating comprises at least two layers whereof one layer does not substantially modify light transmission and reflection of said coating formed of a material selected among stainless steel oxide, and the oxides of metals in columns VIb, VIIb, and VIII of the periodic table of elements and their alloys. Said protective layer enables to improve the chemical durability of numerous coatings comprising it without significantly modifying their light transmission and reflection properties.
