| 简介 |
A process for producing a wipe-proof anti-reflection layer on a borosilicate glass body is described, in which the borosilicate glass body is coated with a coating solution having a composition of 1-6% by weight of HCl, 0.5-7% by weight of SiO2 sol (solids content), 0.5-5% by weight of H2O, and 85-98% by weight of a readily volatile water-soluble organic solvent. The borosilicate glass body that is to be coated contains, in % by weight based on oxide content : 63-76 of SiO2, >11-20 of B2O3, 1-9 of Al2O3, 3-12 of alkali metal oxide(s), 0-10 of alkaline earth metal oxide(s), 0-2 of ZnO, 0-5 of TiO2, 0-1 of ZrO2, 0-1 of Nb2O5, and 0-1 of WO3. |
