Glass substrate with at least one reflective metal coating with comp. no ser tertiary resistance to corrosion, a method for its preparation and its applications

摘要

a reflective product like a mirror includes a reflective, isolated on a glasunterlage,.in order to protect this, if he has a reflective layer of silver, this coating with an acidified aqueous solution of tin (ii) salt treated, what solution free of opaleszenz, which reduces the number of zinnatomen in a surface layer of this it metallu00fcberzugs increases.$a particularly includes a such a reflective layer of silver, and has a surface layer with a number of zinnatomen which is greater in comparison to the number of zinnatomen (if any) in the underlying class and who igstens a zinnatom per 100 metallatome,making such an improved resistance against corrosion, is given.a method of producing a $a reflective product from a reflective, isolated on a glasunterlage comprises the following steps: formation of a metallu00fcberzugs with a reflective layer of silver on a surface of the document.the metallu00fcberzugs contact with a freshly prepared acidified aqueous behandlungslu00f6sung of tin (ii) salt for the number of zinnatomen in a surface layer of the layer of metal to increase the solution free of opaleszenz, and washing and drying of the b ehandelten metallu00fcberzugs.
