Abstract
The present invention relates to a process for depositing an anti-reflective layer on a transparent flat substrate comprising the steps of providing a liquid coating composition comprising at least one solvent, at least one inorganic oxide precursor, and at least one pore forming agent; applying the coating composition to the substrate; drying the applied coating layer, and curing the coating layer; wherein during drying a gas flow is provided to the substrate at a flow rate of between 0.2 and 6 m/s. The advantage of this process is that defects visible in edge areas of the coated substrate can be significantly reduced.
