  • Patent number: 5017255
    Abstract: A method of forming a transferable pattern or image of an inorganic film by coating an embossed substrate with an inorganic layer, that may comprise one or more films, over both recessed and raised surface portions, adhesively laminating a transfer substrate to the inorganic layer coating the raised surface portions of the embossed substrate and separating the embossed substrate and the transfer substrate. The adhesive is selected such that the bond between the transfer substrate and the inorganic film on the raised surface portions is greater than the bond between the inorganic layer on the raised surface portions and the embossed substrate.The embossed substrate resulting after removal of the inorganic layer coating the raised surface portions may be modified to include additional inorganic layers over the recessed surface portions by tinning or electroplating methods such that this thickened inorganic layer may also be transferred from the embossed substrate to a transfer substrate as set forth above.
