Substrate having a functional coating and a temporary protection layer

An article comprising a substrate comprising two main faces defining two main surfaces separated by edges, said substrate bearing:

• a functional coating deposited by magnetron sputtering deposited on at least one portion of one main surface, said functional coating including an upper layer having a thickness from 1 nm to 40 nm, and
• a temporary protective layer deposited on at least one portion of the functional coating, wherein,
• the temporary protective layer is deposited directly in contact with the upper layer of the functional coating,
• the temporary protective layer has a thickness of at least 1 micrometer,
• the temporary protective layer is not soluble in water, and
• the temporary protective layer is obtained from a composition comprising (meth)acrylate compounds,
• the substrate bearing the functional coating has not undergone a heat treatment at a temperature above 400° C.
