Document Type and Number:
WIPO Patent Application WO/2019/008282
Kind Code:
A3
Abstract:
The invention relates to a method for producing a material comprising a textured glass substrate coated on at least one of the textured surfaces thereof with an anti-reflective sol-gel-type coating comprising porous silica, said method comprising the following steps: a step of applying a solution containing at least one silica precursor and at least least one pore forming agent to the at least one textured surface of the substrate; and subsequently subjecting same to a heat treatment in order to strengthen the anti-reflective coating, said method being such that, prior to the application step, the glass substrate is subjected to a pre-heating step such that the at least one textured surface intended to be coated with the anti-reflective coating has a temperature within a range from 30 to 100°C, in particular 50 to 80°C, immediately prior to the application step.
