| 摘要 |
The present invention relates to essentially transparent glazings comprising a system of films deposited under vacuum by magnetron, and having antisun and/or low-emission properties, comprising as protective surface layer a layer based on titanium oxide and on at least one other metal oxide of high hardness from the group comprising: ZrO2, SiO2, Cr2O3. The glazings according to the invention are of a nature to withstand a heat treatment at 550° C. for 5 minutes without giving rise to the presence of optical effects, especially of coloration or iridescence. These glazings are termed toughenable. |
