    Patent number: 4992087
    Abstract: Process for the production of a tempered or bent glass plate provided with a transmission-reducing coating, in which to one side of the glass plate is applied at least one metal coating with a preponderant content of at least one metal or a metal alloy from elements of numbers 22 to 28 of the Periodic System of elements and to the latter is applied a metal-containing protective coating and subsequently a thermal tempering or bending process is performed in air at a temperature between approximately 580.degree. C. and 680.degree. C. and in which the thickness and material of the protective coating are selected in such a way that during the tempering or bending process there is no significant oxygen diffusion to the metal coating, characterized in that in the case of a rear arrangement of the reflecting metal coating made opaque through an adequate thickness, the protective coating is formed by an alloy of Al with Ti and/or Zr, the glass plate produced according the same and the use thereof.
