摘要： The present invention relates to an element comprising a surface area with a specific, optically effective surface relief microstructure (12). The surface relief microstructure has a surface modulation of top regions (13) and bottom regions (14), wherein in a first lateral direction of the surface area there is in average at least one transition from a top to a bottom region or vice versa within every 20 micrometer, and in a second lateral direction of the mask, which is perpendicular to the first direction, there is in average at least one transition from a first to a second zone or vice versa within every 200 micrometer. In the microstructure, (i) in the first direction the lateral arrangement of the transitions is non-periodic, and (ii) the top regions substantially lie in the same top relief plateau (15) and the bottom regions substantially lie in the same bottom relief plateau (16). Through scattering effects, the surface relief microstructures are suitable to display images with a positive-negative image flip, which advantageously have a distinct and saturated color appearance but at the same time do not show any rainbow colors. The invention also relates to methods for making such elements as well as to security devices comprising such elements.

摘要： The invention relates to optical films and coatings and more specifically to a film or coating acting as a diffuse reflector or a diffuser, which is formed of a monomer-corrugated film or coating, which, when illuminated with CIE standard illuminant D65 under a selected direction has the property that within a desired angular range of observation of at least five degrees the difference in the CIE chromaticity coordinates (x, y) of said diffuse reflector or diffuser and of standard white BaSO 4 is not more than 0.05 and the gain in brightness compared to standard white BaSO 4 is not less than two. Diffusers and reflectors according to the invention are capable to redirect the transmitted or reflected incident light into a desired off-specular viewing cone whose shape is defined by the groove topology. The sizes (both grooves period and height), the vertical profile of the corrugations as well as their distributions and volume fraction can be adjusted via the MC-process. It can be used to control the spatial distribution of transmitted and reflected light and to achieve a desired state of polarization and whiteness.

摘要： A liquid crystal electrooptical element comprises a pair of substrates (20, 21) positioned between a pair of polarising plates, electrodes defining pixel areas (1) and alignment layers disposed on the respective opposing inside surfaces of said substrates (20, 21) and a chiral nematic liquid crystal sandwiched between said pair of surfaces. At least one of the alignment layers is patterned in such a way that the azimuth or pretilt or both alignment directions (14 to 17, 16 to 18) are different at the substrate interfaces suppressing the growth of the ground state of the liquid crystal. When an initial electrical pulse is applied, one of the at least two bistable states is reached, wherein the contrast ratio between said bistable states is two or greater. A device with these elements is long-term bistable and does not require electronic refreshing as long as the displayed information is not changed. Therefore, the power consumption of this bistable device is minimal.
