TRANSFER FILM AND METHOD FOR TRANSFERRING A BARRIER LAYER ONTO A SUBSTRATE

Abstract: the present invention relates to a transfer film for applying a barrier layer onto a substrate. the transfer film comprises a carrier film, on which a layer sequence is applied consisting of at least one lacquer layer, made of a barrier lacquer, and an inorganic layer, wherein the adhesive forces between the lacquer layer and the carrier film are lower than the adhesive forces between the lacquer layer and the inorganic layer. the transfer film is characterized in that the barrier lacquer comprises a polymer matrix having a hydrophilic component and a hydrophobic component, of which the hydrophilic component significantly outweighs the hydrophobic component. the transfer film allows a barrier layer having effective barrier properties to be transferred onto target substrates, for which this was previously technically impossible or economically impractical.
