A vehicle window, includes at least one transparent glass pane and an IR-reflective coating on a surface of the glass pane, wherein the IR-reflective coating includes n metallic layers and (n+1) dielectric layer modules, wherein the layer modules are implemented as dielectric layers or layer sequences and wherein the layer modules and the metallic layers are arranged alternatingly such that each metallic layer is arranged between two layer modules, where n is a natural number greater than or equal to 1, wherein each metallic layer is implemented as a discontinuous layer of metal nanocrystals, which has regions that are occupied by metal nanocrystals and regions that are not occupied by nanocrystals. The uppermost layer module has a dielectric anti-reflection layer with a refractive index of at most 1.7.

A method for producing a coated and printed glass panel, includes providing a glass substrate having a metal-containing coating on at least one first surface and a polymeric protective layer arranged on this metal-containing coating, removing the temporary polymeric protective layer and the metal-containing coating only in a predetermined region, applying a ceramic ink in the predetermined region, wherein the removing is carried out with a laser and the polymeric protective layer and the metal-containing coating are intact outside the predetermined region after the removing.

Method for producing a printed, coated panel

A method for producing a coated and printed glass panel, includes a) providing a glass substrate having a metal-containing coating on a first surface and a polymeric protective layer with a thickness d arranged on this metal-containing coating, b) removing the polymeric protective layer in a first region using a carbon dioxide laser, c) removing the metal-containing coating within the first region only in a second region using a solid-state laser such that an edge region is created, in which the metal-containing coating is intact and in which the polymeric protective layer was removed in step b), d) applying a ceramic ink only in the first region, e) heat treating the glass panel at &#x3e;600&#xb0; C., wherein the polymeric protective layer is removed on the entire first surface, in the edge region, the metal-containing coating is dissolved by the ceramic ink lying above it, and the ceramic ink is fired.

A transparent pane having at least one transparent substrate and at least one an electrically conductive coating on at least one surface of the transparent substrate. The electrically conductive coating has at least two functional layers arranged one on top of another. Each functional layer contains: a layer of optically highly refractive material; a smoothing layer above the layer of optically highly refractive material; a lower adapting (matching) layer above the smoothing layer; an electrically conductive layer above the lower adapting layer; and an upper adapting (matching) layer above the electrically conductive layer. The lower adapting layer and/or the upper adapting layer contain a homogeneously distributed getter material. At least one lower adapting layer and/or upper adapting layer containing the getter material is in direct contact with the electrically conductive layer.
