Abstract
The present invention relates to a process for applying an optical coating to a substrate comprising the steps of (a) preparing an optical coating formulation comprising a solvent component and a film forming component; (b) using a die coater to form a coated substrate by applying the optical coating to a substrate, where the applied optical coating forms a wet film thereon having a thickness from 8 μm to 100 μm; (c) drying the coated substrate, where the coated substrate is in a substantially horizontal plane thereby converting the wet film to a dry film having a thickness of less than 1 μm. The optical coating formulation comprises greater than 0.3 wt % to no more than 10 wt % solids relative to the total weight of the optical coating formulation. The coated substrate may be optionally cured.
