Printing diffraction gratings on polymer substrate |
abstract |
The present invention relates to a method for forming a surface relief microstructure, especially an optically variable image (an optically variable device) on a paper substrate comprising the steps of: nA) applying a curable composition (varnish) to at least a portion of the frontside of the paper substrate; nB) contacting at least a portion of the curable composition with surface relief microstructure, especially optically variable image forming means; nC) curing the composition by using at least one UV lamp which is arranged on the backside of the paper substrate; nD) optionally depositing a layer of a transparent high refractive index material and/or a metallic layer on at least a portion of the cured composition, wherein the lamp having emission peak(s) in the UV-A and near VIS range range and the curable composition comprises at least a photoinitiator which absorbs in the UV-A region and preferrably in the near VIS range, a paper product obtainable using the method and an apparatus for forming a surface relief microstructure on a paper substrate. Surface relief microstructures, such as holograms may be replicated rapidly and with accuracy on a paper substrate by using the method and the apparatus of the present invention. |
