Definitions

  • the invention relates to a laminated pane with a heating resistance layer, and to a laminated pane arrangement which includes such a laminated pane. It also relates to a vehicle with such a composite pane and a method for producing the composite pane.
  • Composite panes made of two or more glass or polymer panes are used in vehicles as windshields, rear windows, side windows and roof windows.
  • One or more functional coatings which have infrared-reflecting properties, anti-reflective properties or low-E properties can be arranged on individual sides of the panes.
  • the coatings can also be used as heatable, electrically conductive coatings. The heat generated by the coating can quickly remove condensed moisture, ice and snow.
  • Heatable and in particular transparent coatings usually comprise a plurality of metallic layers, in particular based on silver, which are applied alternately with dielectric layers. These coatings are electrically conductively connected to a voltage source, so that a heating current can flow through such a coating.
  • Silver-containing transparent coatings are known, for example, from WO2013/104439 A1 and WO2017/198362 A1.
  • DE 10022409 C1 discloses a method for producing a composite pane with a transparent anti-corrosion surface coating.
  • the object of the present invention is to provide a further improved laminated pane with a heating resistance layer, in which the heating resistance layer is arranged on a surface of the first pane, in particular an outer pane.
  • the object of the present invention is achieved according to the invention by a laminated pane with a heating resistance layer according to claim 1 . Preferred embodiments emerge from the dependent claims.
