the invention it comprises a support 20 of clear or tinted glass for example an enamel border 21 preferably black deposited by silk screening on the periphery of the glass support a conductive layer with a silver base 22 deposited by silk screening on the enamel border 21 and slightly set back relative to the edge of the glass support an electrically conductive coating 23 and a plastic sheet 24 comprising at least one polyurethane layer as defined above the stages for the production of such a glazing can be those described above for the glazing of fig1 particularly for the deposition of enamel border 21 and electroconductive coating 23 and the assembly with plastic sheet 24 unlike the glazing of fig1 and 1a the electric power lead in strips are in this embodiment of fig2 conductive strips with a silver base 22 instead of copper foils in this case conductive strip 22 with a silver base deposited by silk screening from a composition as described above can be applied after the baking of black enamel 21 it also can be deposited on black enamel 21 immediately after the drying of the enamel the baking of enamel 21 and conductive strip 22 then taking place simultaneously as indicated.
