Abstract
An electrically heatable laminated glazing system is disclosed comprising two single glass panes (1,4) bonded together by a thermoplastic film of polyvinyl butyral (3). One of these two panes (1) bears a layered construction (2). The layered construction comprises a conducting silver layer (22), an anti-reflective cover layer (23) of zinc oxide disposed on the silver layer (22), and a bonding layer (24) utilized to improve a bond between the polyvinyl butyral film (3) and the anti-reflective covering layer (23). The bonding layer comprises one of the metals in groups IV, V, or VII of the periodic system or an oxide of these metals.
