Abstract
Method for providing a patterned thin film on a flexible web-like substrate having at least one surface. A patterned release coating which carries the desired pattern is deposited on the surface and has openings therein through which the surface of the substrate is exposed. A thin film is deposited over the patterned release coat and onto the portions of the surface exposed through the openings. The patterned release coating is then removed mechanically along with the thin film portions carried thereby to provide a patterned thin film on the substrate. The mechanical removal may be accomplished by advancing the coated substrate through a solvent while brushing the substrate, subjecting the substrate to high velocity air, or contacting the substrate with the adhesive layer of a web.
