Abstract: The present invention relates to a coated substrate comprising: a substrate; a soft coating provided on at least a part of at least one face of the substrate; a protective sol-gel coating provided on at least a part of said face above the soft coating, to a process for making such coated substrate and to glazing units comprising such coated substrate.

Abstract: The present invention concerns a process to increase the mechanical and chemical resistance of a hydrolyzable network-forming silica gel coating provided on the surface of a substrate. According to the invention, a coating composition comprising a hydrolyzable, network-forming silica gel doped with a precursor of bismuth or cerium oxide is applied on the surface of the substrate. The present invention concerns also the product obtained by the said process.

Abstract: A glass sheet comprising at least one etched surface having a surface roughness defined, when measured on an evaluation length of 2 mm and with a Gaussian filter of which the cut-off wavelength is 0.8 mm, by 0.02?Ra?0.4 microns and 5?RSm?30 microns. The glass sheet has excellent anti-sparkling properties together with an anti-glare effect. The texturing of the glass sheet may obtained by the process of carrying the glass sheet horizontally on a conveyor, pre-treating the surface to remove defects that may prevent subsequent uniform etching, etching the surface with aqueous solution containing hydrofluoric acid spread in an uniform layer over the surface of the sheet, maintaining the etching solution until the etching is ended, and drying the etched sheet.

Abstract: The invention relates to a glass sheet comprising at least one etched surface having a surface roughness defined, when measured on an evaluation length of 12 mm and with a Gaussian filter of which the cut-off wavelength is 0.8 mm, by: 0.02?Ra?0.4 microns, 5?RSm?30 microns, said glass sheet having the following optical properties, when measured from said etched surface: a haze value of from 1 to 40%; a clarity value of from 50 to 100%; a gloss value at 60° of from 20 to 110 SGU. Such a glass sheet which is particularly suitable for display applications as cover glass. In particular, the glass sheet of the invention has excellent anti-sparkling properties together with an anti-glare effect. Moreover, the glass sheet of the invention also combines anti-glare and anti-sparkling properties with a “soft touch”.
