The metal layer has at least one continuous cut-out section and the colored layer is arranged in the area of the cut-out section.

Provided is a carrier-attached metal foil which can suppress the number of foreign matter particles on the surface of a metal layer to enhance circuit formability, and can keep stable releasability even after heating at a high temperature of 240 C. or higher (for example, 260 C.) for a long period of time. The carrier-attached metal foil includes a carrier, a release functional layer provided on the carrier, the release functional layer including a metal oxynitride, and a metal layer provided on the release functional layer.

The present invention discloses a laminated glazing for a vehicle having thermal insulation properties. To solve antireflection issues, the glazing is comprised of a second glass layer having texturing features onto its external surface and a low-emissivity coating disposed onto said texturing features. The texture of the glass and the design of the low-E coating are tuned in such a way as to ensure a good adhesion of the coating during high-temperature bending process and, at the same time, to enable its low level of emissivity. The glazing may comprise a color and/or solar control coating onto the internal surface of the first glass layer. The glazing may also comprise photovoltaic cells and/or visible light transmission elements. In another embodiment still, the low-E coating onto the texturing features is tuned to serve as an image projection element.

Provided is a transparent substrate with a multilayer thin film coating, in which the multilayer thin film coating includes a lower dielectric layer, a lower protective layer, a metal functional layer having an infrared reflection function, an upper protective layer, and an upper dielectric layer, which are sequentially laminated on the transparent substrate, the thickness of the metal function layer is 12 nm or more, and the thickness of the lower protective layer is larger than that of the upper protective layer and the thickness of the lower protective layer is 2 nm or more.

An architectural glass for use in a greenhouse comprising a substrate having a coating, the coating comprising a first dielectric layer, a metal layer over the first dielectric layer, a second dielectric layer over the metal layer, and a first protective overcoat over the second dielectric layer, wherein the first protective overcoat comprises silica and alumina. A back surface of the glass substrate can be coated with a scattering layer and a second protective overcoat. The architectural glass can be a monolithic glass or a component in an insulated glass unit.

Multilayer metallo-dielectric energy control coatings are disclosed in which one or more layers are formed from a hydrogenated metal nitride dielectric, which may be hydrogenated during or after dielectric deposition. Properties of the multilayer coating may be configured by appropriately tuning the hydrogen concentration (and/or the spatial profile thereof) in one or more hydrogenated metal nitride dielectric layers. One or more metal layers of the multilayer coating may be formed on a hydrogenated nitride dielectric layer, thereby facilitating adhesion of the metal with a low percolation threshold and enabling the formation of thin metal layers that exhibit substantial transparency in the visible spectrum. Optical properties of the coating may be tuned through modulation of metal-dielectric interface roughness and dispersion of metal nanoparticles in the dielectric layer. Electrical busbars and micro-nano electrical grids may be integrated with one or more metal layers to provide functionality such as de-icing and defogging.
