Claims
- 1. A process comprising:
pressing a master into a multi-layered structure,
said master having a surface facing said multi-layered structure, said surface comprising an area having a protruding micro-structured pattern, said multi-layered structure comprising at least one supporting layer and at least one top layer, said at least one top layer being positioned between said master and said at least one supporting layer, wherein
at least part of said micro-structured pattern penetrates through said at least one top layer into said at least one supporting layer.
- 2. The process of claim 1, wherein said at least one supporting layer includes a polymer layer.
- 3. The process according to claim 2, wherein said polymer layer is in the solid state during said pressing.
- 4. The process according to any one of claims 1-3, wherein said at least one top layer includes a layer capable of conducting electricity.
- 5. The process according to any one of claims 1-4, further comprising removing said master from said multi-layered substrate.
- 6. The process according to any one of claims 1-5, further comprising removing said at least one supporting layer from said at least one top layer.
- 7. The process according to any one of claims 1-6, wherein said multi-layered structure comprises at least two top layers.
- 8. The process according to claim 7, further comprising removing at least one top layer from said at least two top layers after said pressing.
- 9. The process according to any one of claims 1-8, wherein each of said at least one top layer has a thickness of between 1 nm-100 μm.
- 10. The process according to any one of claims 1-9, wherein said microstructured pattern comprises two adjacent protruding edges, said two adjacent protruding edges being spaced apart less than 100 μm.
- 11. The process according to any one of claims 1-9, wherein said microstructured pattern comprises two adjacent protruding edges, said two adjacent protruding edges being spaced apart less than 10 μm.
- 12. The process according to any one of claims 1-9, wherein said microstructured pattern comprises an array of protruding edges and wherein each protruding edge in said array is spaced apart less than 1 mm from an adjacent protruding edge in said array.
- 13. An object obtained by a process according to any one of claims 1-12.
- 14. The object of claim 13, wherein said object is selected from the group consisting of microelectrodes, optical filters, polarizers, polarization-dependent color filters, transflectors, and security features.
