Abstract
A laminated glazing is prepared by a providing an electroconductive layer on side 3, the sides of such a glazing being conventionally numbered from 1-4 starting from the outside of the glazing when mounted on a vehicle, towards the inside. The electroconductive layer is formed by powder deposition and pyrolysis to form a ITO layer on a glass pane, which is subsequently bent such that the surface bearing the ITO layer is convex. This glass is laminated with a glass of the same curvature, between which panes is sandwiched a plastic interlayer. On the side of the interlayer facing the electroconductive layer, current lead strips, in the form of metal tinsel, are provided, such that upon lamination, the metal lead strips are in electrical contact with the electroconductive layer and lead to a source of electricity. The resulting window is produced more simply, more reliably, and exhibits improved defogging.
