Abstract

The invention relates to a substrate comprising two main faces defining two main surfaces separated by edges, said substrate bearing a functional coating deposited on at least one portion of one main surface and a temporary protective layer deposited on at least one portion of the functional coating. The temporary protective layer, cured by drying, by UV irradiation or by an electron beam, has a thickness of at least 1 micrometer and is not soluble in water. This temporary protective layer is obtained from a liquid composition comprising (meth)acrylate compounds selected from monomers, oligomers, prepolymers or polymers comprising at least one (meth)acrylate function.
