Disclosed herein is a method for forming a surface relief microstructure, including the steps of A) applying a curable composition to at least a portion of the frontside of the paper substrate, B) contacting at least a portion of the curable composition with surface relief microstructure, C) curing the composition by using at least one UV lamp which is arranged on the backside of the paper substrate, and D) depositing a metallic layer, and optionally a layer of a transparent high refractive index material, on at least a portion of the cured composition, wherein the UV lamp has an emission peak in a UV-A range of 320 nm to 400 nm and additionally in a near VIS range of 400 nm to 450 nm, the curable composition comprises a photoinitiator which absorbs in the UV-A range and also in the near VIS range.

A security device has a support substrate of a first material having a softening temperature t1 and an embossed layer of a second different material supported by the support substrate having a softening temperature t2, wherein t2<t1. A thin film coating deposited directly upon the embossed layer, wherein the embossed layer is capable of being dissolved in a dissolving agent and wherein the thin film coating is not dissolvable by said dissolving agent. There is not need for an additional release layer as the second different material is dissolvable and allows flakes to be formed by dissolving the second layer.

A method and an apparatus for forming a surface relief microstructure, especially an optically variable image on a paper substrate are provided, the method comprising the steps of: A) applying a curable composition to at least a portion of the frontside of the paper substrate; B) contacting at least a portion of the curable composition with surface relief microstructure, especially optically variable image forming means; C) curing the composition by using at least one UV lamp (1, 2, 3) which is arranged on the backside of the paper substrate; D) 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 (1, 2, 3) having emission peak(s) in the UV-A and near VIS range and the curable composition comprises at least a photoinitiator which absorbs in the UV-A region and preferably in the near VIS range. A paper product obtainable uses 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.

A gaming device is described that provides a number of different methods for cashing out credit balances from a gaming device. These methods include providing incentives, such as benefits, to a player for selecting particular monetary forms in which to receive the cash out. Non-preferred cash out forms may be associated with disincentives, such as penalties, to dissuade players from selecting these types of monetary transfers. In certain embodiments, incentives and disincentives may be associated with a variety of available monetary forms for cash out.

A door frame for a vehicle includes a holographic door sill panel in a lower door frame portion, a suitable lighting assembly in a lateral door frame portion, a holographic door sill panel suitable for such a door frame, as well as a system that is composed of the holographic door sill panel and the lighting assembly and suitable for such a door frame.

Disclosed is a security film, including: a substrate layer, a nano-wire grid polarizer layer having a line grid pattern, and at least one information identification layer, wherein the substrate layer, the nano-wire grid polarizer layer and the information identification layer are stacked so that at least one information identification layer is provided in at least one position selected from among a position on an outer surface of the substrate layer, a position between the substrate layer and the nano-wire grid polarizer layer, and a position on an outer surface of the nano-wire grid polarizer layer. This invention can provide a high-dimensional information storage medium by combining a nano-wire grid polarization film, manufactured via a nano-imprinting process, with various security elements, making it possible to enhance security against illegal counterfeiting and copying.

A display including a relief structure forming layer having a major surface with a relief type diffractive structure that displays a three-dimensional object as a diffraction image; and a reflective layer at least partially covering a region of the major surface where the diffractive structure is provided. A portion of the diffractive structure in a first region includes first and second linear parts forming a first lattice, and first parts arranged in respective gaps of the first lattice. The first and second linear parts each having a solid line shape form a first pattern. A portion of the diffractive structure in a second region includes third and fourth linear parts alternately arranged in the width direction thereof. The third linear parts each having a dashed line shape and the fourth linear parts each having a dashed or dotted line shape form a second pattern.

For the production of embossed microstructures in radiation-curing materials, use is made of a micro embossing form fixed to a reflective or scattering cylinder surface. Via a press nip, the micro embossing form comes into contact with the substrate guided over a cylinder or a deflection roller. The radiation-curing material is acted on in one or both pockets, before or after the press nip, with radiation which penetrates into the press nip by reflection or scattering.

A light modulation element reproduces a light image in a specific color other than iridescence where white light is incident, without a layer that selectively transmits or reflects a specific wavelength band, and clearly reproduces a desired light image by reducing an influence of 0th-order diffracted light, and an information recording medium including the same. The light modulation element includes a factor element that reproduces a light image by modulating a phase of incident reproduction light, and has an uneven surface. A maximum diffraction efficiency Dmax in a wavelength band of between 380 nm and 780 nm in wavelength distribution of first-order diffracted light and of negative first-order diffracted light with respect to diffraction efficiency for the factor element has a local maximum value with a full width at half maximum FWHM of 200 nm or less in wavelength distribution with respect to diffraction efficiency having the maximum diffraction efficiency.
