A continuous self-metered process of forming a multilayer film comprising at least two superimposed polymer layers comprising the steps of: providing a substrate; providing two or more coating knives which are offset, independently from each other, from said substrate to form a gap normal to the surface of the substrate; moving the substrate relative to the coating knives in a downstream direction, providing curable liquid precursors of the polymers to the upstream side of the coating knives thereby coating the two or more precursors through the respective gaps as superimposed layers onto the substrate; optionally providing one or more solid films and applying these essentially simultaneously with the formation of the adjacent lower polymer layer, and curing the precursor of the multilayer film thus obtained; wherein a lower layer of a curable liquid precursor is covered by an adjacent upper layer of a curable liquid precursor or a film, respectively, essentially without exposing said lower layer of a curable liquid precursor.
