Abstract

An electrically heatable car glazing (1) of laminated glass has a transparent surface coating (8) as the heating resistor. The outer glass plate (2) is provided, along the circumference of its inner side, with a frame-like heat-curing coating (6), and bus bars (7) of an electrically conductive heat-curing paint are provided on the frame-like coating. The surface coating (8) is placed over the bus bars (7), and metal foil bands (10) are placed above the bus bars (7) on the surface coating. The end portions (11) of the metal foil bands (10) are provided with a tear-proof plastic envelope (12), which is bonded to the glass plate (2).
