Abstract

An electrically heated automobile glazing has a surface coating (14) serving as resistance heater and a frame-shaped decorative layer (15) of an opaque bakable enamel. Frame-shaped decorative layer (15) consists of an electrically conductive bakable enamel and is in electrically conductive contact with surface coating (14). Current supply conductors (16) are made of thin strips of metal or metallic strips and are in electric contact with decorative layer (15). Surface coating (14) can be deposited between the surface of the glass and decorative layer (15) or between decorative layer (15) and current supply conductor (16).
