Layered films for transparent substrates

A stack of layers for the coating of transparent substrates, particularly glass substrates, has at least unecouche composite metal oxide produced in particular by reactive sputtering and which contains Zn oxide and del'oxyde Sn. Relative to the total amount of metal, the composite metal oxide layer preferably contains 0.5 to 6.5% by weight of one or more of the elements Al, Ga, In, B, Y, La, Ge , Si, P, As, Sb, Bi, Ce, Ti, Zr, Nb and Ta. Decouches in a stack which has a silver layer as the functional layer, the composite layer of metal oxides can be used WHILE upper anti-reflection layer and / or bottom, as a barrier layer to diffusion, as a sublayer of a coucheanti-reflection and / or as top cover layer.
