This invention is directed to a process for forming coatings comprising light metal fluorides on a substrate. More particularly, the coating comprising light metal fluorides is preferably made using sol-gel techniques and may comprise a concentration gradient of the light metal fluorides across the thickness of the coating to provide it with unique anti-reflective properties.

Process for forming anti-reflective coatings comprising light metal

Anti-reflective coatings comprising light metal fluorides

Three-layer, low color purity, anti-reflection coatings reduce the reflection of visible light rays and display a low color purity when glazings carrying such coatings are oriented at high angles of incidence with respect to a source of visible light. The reflectances are comparable and the color purity values are lower for such glazings, when compared with conventional glazings coated with 1/4-178 -174 wavelength anti-reflection coatings.

Low color purity, anti-reflection coatings for transparent glazings

A blue glass composition comprises conventional soda-lime-silica glass ingredients and specific amounts of Fe.sub.2 O.sub.3, Co.sub.3 O.sub.4, NiO, and optionally Se, resulting in an Illuminant C transmittance of 54% .+-.3% at one quarter inch thickness, a dominant wavelength of 482 nm.+-.1 nm, and a color purity of 13% .+-.1%.

Methods of making electrically heated windows (10, 100) and products produced thereby. In an embodiment of the method of our invention for producing a product of laminated construction (10), a pair of glass sheets (12, 20) are laminated together by an interposed laminated interlayer (18). This lamination is carried out in a manner that a first (12) of the pair of glass sheets defines both a first glass surface forming the outer surface of the window and a second glass surfaces in juxtaposition with the laminating interlayer, and a second (20) of the pair of glass sheets defines both a third glass surface in juxtaposition with the laminating interlayer and a fourth glass surface forming the inside surface of the window. An electrically conductive coating (16) is formed in association with one of the glass surfaces in juxtaposition with the laminating interlayer. The product is improved by carrying out in the method of manufacturing the same the step of forming at least one sol-gel antireflective coating (14) on at least one of the glass surfaces other than the first glass surface. The sol-gel antireflective coating improves the overall transmittance of light in the visible wavelength through the electrically heated window. The specification describes several different embodiments for both the method of the invention and the product produced thereby.
