[0130] The final layers were produced as follows: 10×20 cm format float glass sheets carefully cleaned in a washing operation were immersed in the various impregnating solutions. Then, the sheet was pulled again at a rate of 6 mm / sec, and the moisture content of the ambient atmosphere was 4 g / m 3 up to 12g / m 3 , preferably 8g / m 3 . The solvent was subsequently evaporated at 90 to 100° C., after which the layer was fired at 450° C. for 20 minutes. The layer produced in this way has a thickness of about 90 nm.
[0131] Preparation of Example Solutions:
[0132] first dipping solution
[0133] 125 ml of ethanol were introduced. Thereto were added 45 ml of methyl silicate, 48 ml of distilled water and 6 ml of glacial acetic acid under stirring. After the addition of water and acetic acid, the solution is stirred for 4 hours, during which time the temperature must not exceed 40°C. The solution may need to be cooled. The reaction solution was then diluted with 675 ml of eth...
