Claim:
1. A process for depositing an anti-reflective layer on a transparent flat substrate comprising the steps of: a) providing a liquid coating composition having a solids content of up to about 10 mass % and comprising at least one solvent, at least one inorganic oxide precursor, and a core-shell nano-particle with a silica shell and an organic core as a pore forming agent; b) applying the coating composition onto a transparent flat glass plate or sheet as a substrate to thereby form a coating layer on the substrate between edges thereof; c) drying the applied coating layer on the substrate at a drying temperature of ambient conditions or up to 80° C. by providing a flow of gas at a gas flow rate range of between 0.5 and 6 m/s to the coating layer at least along the edges of the substrate and an area adjacent the edges of the substrate; and d) curing the coating layer on the substrate at a curing temperature of from 350° C. to 900° C.
