Abstract:
A method of protecting a substrate having at least one light transmitting surface and at least one functional coating from mechanical damage, comprising the steps of:providing a substrate having at least one light transmitting surface and having a surface with a functional coating over at least a portion of the surface; depositing a liquid coating composition over at least a portion of the functional coating, the coating composition comprising a film-forming polymeric material; and forming a removable protective coating from the coating composition with film forming material, wherein the functional coating is selected from the group consisting of single layer and multiple layer coatings, wherein the functional coating comprises a material selected from the group consisting of one or more metals, non-metals, semimetals, semiconductors, or alloys, compounds, composites, combinations, and blends thereof, wherein the removable protective coating is essentially free of particulate solid spacer material for interleaving when the functional coating is a single layer metal oxide and wherein the film-forming polymeric material comprises polyvinyl alcohol having a degree of hydrolyzation of greater than about 80 percent.
