In a known method for producing an emitter component with a reflector, a flowable aqueous SiO2 slip is produced using a slip method, and the slip is applied onto a quartz glass main part in the form of a slip layer. The slip layer is then dried and glazed, thereby forming a quartz glass layer which is more or less opaque and diffusely reflective. In order to produce an optical component with a reflective layer made of opaque quartz glass with increased reflective optical power, a method is proposed having the steps of: providing a main part with a surface which is at least partly coated with a reflective layer made of opaque glass, compressing a surface region of the reflective layer made of opaque glass, and applying a mirror-reflective layer on at least one part of the compressed surface region.

A method of manufacturing a variable reflectance mirror reflective element suitable for use in a vehicular rearview mirror assembly includes providing a front glass sheet and a plurality of rear glass substrates, and joining and spacing the rear glass substrates at the front glass sheet via perimeter seals. After the rear glass substrates are joined with the front glass sheet, the front glass sheet is cut to form a plurality of front glass substrates. A back plate is attached at the rear side of each of the rear glass substrates. After cutting the front glass sheet, the back plate of the respective rear glass substrate and cut front glass substrate portion is fixtured at a finishing tool, which processes the cut edges of at least the respective front glass substrate to provide a finished perimeter edge of the front glass substrate to form a variable reflectance mirror reflective element.

A process for obtaining a decorative mirror includes reflective regions forming a pattern and non-reflective regions, the process including providing a sheet of soda-lime-silica glass coated with a reflective coating on the entirety of one of the faces thereof, then applying a composition including a phosphate salt to the reflective coating, solely in application regions, the application regions being intended to become the non-reflective regions, then tempering the glass sheet, in which the glass sheet is subjected to a temperature of at least 550° C., causing the reflective coating to dissolve in the application regions so as to form the non-reflective regions in which the glass sheet is not coated.

A head-up display system with an imaging unit for generating an image on a projection surface is described. The projection surface is provided for reflecting at least a part of the image. The projection surface includes a transparent screen having a transparent substrate and at least one electrically conductive coating with at least one functional layer on at least one surface of the transparent substrate.

A solar reflective mirror includes a parting film between solar reflecting sublayers to improve optics and stability of the solar mirror. The coating stack of the solar reflector mirror is encapsulated to increase the useable life of the solar mirror, and to eliminate the need for a permanent protection overcoat. Omission of the PPO film which is electrically non-conductive makes the coating stack electrically conductive eliminating the need for a two layer encapsulant when the encapsulant is e-coated. Another feature of the invention is applying the base coat of the encapsulant over the marginal edges of the PPO film leaving a center section without coverage and adding the top coating of the encapsulant over the base coat and the uncoated area.

An article for reflecting solar energy includes a coating stack having solar reflecting films and metal oxide films, the coating stack applied on a major surface of a glass substrate, and a protective overcoat comprising a first and a second surface, wherein the first surface of the protective overcoat is disposed toward the solar reflective films and metal oxide films; and a polymer encapsulant over outer wall surfaces of the coating stack, the second surface of the protective overcoat and over peripheral edges of the coated article, the encapsulant having a base layer, a top layer and metallic corrosion-inhibitive material in the base layer.

A coated article is provided for use in a surveillance window or the like. The coated article is a second surface one-way mirror that allows an observer(s) on an observer side to be able to see an object(s)/subject(s) on the opposite side of the coated article, but a viewer on the opposite side cannot reasonably see through the coated article to view things on the observer side of the coated article. The second surface mirror is designed to have a high glass side visible reflectance (R.sub.GY), and an extremely low film side visible reflectance (R.sub.FY), so that visible transmission (T.sub.vis or TY) of the coated article is lower than the glass side visible reflectance but higher than the film side visible reflectance.

The present application relates to a method for enhancing metal corrosion resistance of a metal deposited on a substrate, the method comprises contacting the metal coated substrate with a treating composition comprising a film forming organic component which treating composition forms a hydrophobic film on the metal coated substrate with a thickness of less than 1 m. Furthermore, the present application relates to a method for making a mirror comprising a substrate having a metal coated thereon, the method comprises contacting the metal coated substrate with a treating composition comprising a film forming organic component which treating composition forms a hydrophobic film on the metal coated substrate with a thickness of less than 1 m. Preferably, the film forming organic component is selected from the group consisting of an aromatic triazole compound and a silicone resin. In addition the present application relates to the products obtainable by these methods.

A mirror includes a transparent substrate, at least one metallic reflecting layer and at least one protective paint layer on the back of the mirror. The mirror also includes an overlayer which is a barrier to corrosive elements, such as sulfides and/or chlorides, with a thickness of less than or equal to 6 m which is located on the protective layer. The process for the manufacture of such a mirror is also described.

A protective film placed on an upper part of a metal film for protecting the metal film placed on a glass substrate. The protective film includes a silica film. The silica film has an extinction coefficient k less than or equal to 110.sup.4, a refractive index n greater than or equal to 1.466 at a wavelength of 632 nm, and a carbon content less than or equal to 3 atomic %.
