  • Patent number: 10849234
    Abstract: Multilayer articles that include electrical circuits are prepared by the adhesive transfer of electrical circuit elements to the surface of an adhesive. A number of different methodologies are used, with all of the methodologies including the use of simple layers of circuit-forming material on a releasing substrate and structuring to generate circuit elements which can be transferred to an adhesive surface. In some methodologies, a structured releasing substrate is used to selectively transfer circuit-forming material, either from protrusions on the releasing substrate or from depressions on the releasing substrate. In other methodologies, an unstructured releasing substrate is used and either embossed to form a structured releasing substrate or contacted with a structured adhesive layer to selectively transfer circuit-forming material.
