- said method comprising the steps of:
- providing a layer of a solution comprising 3,4-ethylene dioxythiophene monomers, an oxidation agent, a base, a photochemical acid generator and a solvent on the substrate,
- exposing the layer to patterned radiation,
- heating said exposed layer thereby forming said first electrically conductive portions in the unexposed areas and said pattern of non-conductive portions in the exposed areas,
- and thereafter electrodepositing a metal layer selectively onto the electrically conductive first portions of said polymer layer from a metal salt solution.
- 6. A method as claimed in claim 5, wherein said polymer layer consists essentially of a polymer selected from the group of poly-3,4-ethylene dioxythiophene, poly-3,4-ethylene dioxythiophene wherein the ethylene group is substituted with a C1-C12 alkyl group, poly-3,4-ethylene dioxythiophene wherein the ethylene group is substituted with an alkoxy group, and oligomers of ethylene dioxythiophene.
- 7. A method of manufacturing a laminated structure comprising an electrically insulating substrate carrying a polymer layer comprising first electrically conductive portions having a sheet resistance of maximally 1000 .OMEGA./square, and a pattern of second non-conductive portions whose sheet resistance is at least a factor of 10.sup.6 higher than that of the conductive polymer in said first portions, a metal layer being electrodeposited onto the electrically conductive first portions of said polymer layer,
- said method comprising the steps of:
