The invention relates to glazing having a conductive coating having one or more data transmission windows for transmitting data to/from electronic devices in a vehicle, in which a deletion line surrounds the data transmission window. The deletion line defines first and second regions of the conductive coating. The first region comprises an electrically heated region and first and second busbars for supplying electrical power. The second region comprises at least one data transmission window. The second region may be electrically isolated from the second busbar so that the second region cannot be electrically heated.

The object of this invention is to provide a laminated automotive glazing having an obscuration area produced by printing the obscuration on a film laminated between at least two layers of plastic interlayers rather than printing and firing an enamel frit onto the glass. This results in a laminate having superior optical quality, higher strength and a lower probability of breakage as compared to a laminate with a black enamel frit obscuration.

A composite pane for a motor vehicle, in particular the front pane, is formed from a first pane and a second pane, which are adhered to one another by way of a film. A coating reflecting infrared rays is applied to the film. The coating has at least one cut-out, within which a transponder is arranged between the two panes. A motor vehicle has a composite pane as described above.
