A layer for protecting an underlying functional coating stack for example a single silver layer or double silver layer Low-E coating stack includes silicon oxynitride or silicon aluminum oxynitride layer. The protective film may have a uniform composition throughout its thickness i. e. homogeneous protective layer, a constantly increasing or decreasing index of infraction throughout its thickness i. e. a graded protective layer, or a combination of all or some of the foregoing i. e. a non-homogeneous protective layer. The graded and non-homogeneous layers may have an outer surface of silicon nitride, silicon aluminum nitride, silicon dioxide, silicon oxynitride or silicon aluminum oxynitride. The protective layer of the invention may be the last layer deposited on the functional coating stack or may have a film deposited thereon.

The present invention is directed to an article with a patterned appearance provided by a visually observable contrast between one or more generally transparent thin film coatings deposited over a substrate. At least one of the deposited coatings exhibits a reflected color and/or contrast and visible differing transmitted color and/or contrast or a plurality of coatings together exhibit different reflected colors and/or contrasts. The coatings are selected from the group of: metals depositable by magnetron sputtering vacuum deposition, chemical vapor deposition, pyrolytic coating, or sol-gel techniques, metal oxide coatings, metal nitride coatings, semi-conductor containing coatings, metal oxynitrides and mixtures thereof. The present invention is also directed to a method of making the articles having a visually observable patterned appearance involving masking and applying the coating or applying the coating and removing a portion of the coating to form the pattern.

The present invention is directed to an article with a patterned appearance provided by a visually observable contrast between one or more genereally transparent thin film coatings deposited over a substrate. At least one of the deposited coatings exhibits a reflected color and/or contrast and visible differing transmitted color and/or contrast or a plurality of coatings together exhibit different reflected colors and/or contrasts. The coatings are selected from the group of: metals depositable by magnetron sputtering vacuum deposition, chemical vapor deposition, pyrolytic coating, or sol-gel techniques, metal oxide coatings, metal nitride coatings, semi-conductor containing coatings, metal oxynitrides and mixtures thereof. The present invention is also directed to a method of making the articles having a visually observable patterned appearance involving masking and applying the coating or applying the coating and removing a portion of the coating to form the pattern.

A method and coating are provided for temporarily protecting a substrate or article during shipping, handling or storage by applying a removable protective coating over at least a portion of the substrate. The substrate may be flat or curved and may have zero, one or more functional coatings. A plurality of substrates with the protective coating of the invention may be arranged in a shipping container so that the protective coating reduces the possibility of damage to the substrate or optional functional coating. In one embodiment, the protective coating is the evaporation or reaction product of an aqueous coating composition containing a polyvinyl alcohol polymer which may be subsequently removed by aqueous washing, thermal decomposition or combustion. In another embodiment, the protective coating is formed by sputtering a substantially carbon coating onto the substrate. The carbon coating is subsequently removed by combustion.

An article includes a substrate, e. g. a glass sheet having a first major surface and an opposite second major surface having a textured surface to provide a predetermined pattern on the second surface of the substrate, and an overlay, e. g. a coating over the pattern. The percent of visible light transmittance, and percent visible light reflectance, of the substrate and the overlay is selected such that the pattern is visible when the article is viewed through one of the surfaces of the substrate or overlay. In one non-limiting embodiment, the substrate is glass and the article has a metallic appearance. In another non-limiting embodiment, the overlay is a transparent coating deposited on the second surface of the glass sheet into grooves of the pattern. Other non-limiting embodiments include the substrate having a Delta % haze of greater than 15%, and a protective overcoat over the coating.

A reflective article, such as a solar mirror, includes a highly transparent substrate having a first major surface and a second major surface. At least one reflective coating is formed over at least a portion of one of the surfaces, e. g. , the second major surface (or, alternatively, the first major surface). The reflective coating includes at least one metallic layer. An encapsulation structure can be formed over at least a portion of the second reflective coating.
