Abstract: An article includes a substrate with two main faces defining two main surfaces separated by edges, the substrate carrying a functional coating deposited over at least a portion of a main surface and a temporary protective layer deposited over at least a portion of the coating. The temporary protective layer has a thickness of at least 1 micrometer. The temporary protective layer made of polyfuran resin is obtained from a liquid composition comprising furfuryl alcohol.
