Abstract: A method for producing a decorative element and uses of a decorative element. A polarizing layer functioning as an analyzer is applied to a transparent optical carrier material and a transparent optical functional layer is applied as an image-forming layer including an optically anisotropic material. By spatially structuring the functional layer, a targeted location-dependent dependency of material properties of the optically anisotropic material is created for producing the image-forming layer. One or several decorative elements produced can each be introduced into a light field of a lighting device in a desired shape, size and quantity and having settable image motifs (image structures) and being disposed at different spatial distances and being freely disposable. The decorative element produced is intended to be used as an architectural element for creating light-optical effects in the exterior area of buildings, as a design element for interior design or for object design.

Abstract: A booklet includes a sheet-like first substrate, and a sheet-like second substrate that is attached to the first substrate. The first substrate includes a light-transmitting region, and an optical functional unit is provided to the light-transmitting region. A latent image is provided to a surface of the second substrate that is opposite to the first substrate at a position corresponding to the optical functional unit. The latent image manifests when the optical functional unit operates by overlapping the first substrate with the second substrate.

Abstract: An identification medium can be used in an opening label, clearly show signs of it having been opened, and also have a superior authenticity-confirming function. The identification medium has a structure including, in the following order as seen from the side of observation: an optical function layer that generates a color shift, a separation layer that is partially formed, a printed layer, and an adhesive layer, in which when an adhesive strength between the adhesive layer and an adherend is set to be Xa, an adhesive strength between the adhesive layer and the printed layer is set to be Xb, and an adhesive strength at a portion in which the separation layer is laminated between the optical function layer and the printed layer is set to be Xc, the adhesive strength of each part is set to satisfy Xa>Xb>Xc or Xb>Xa>Xc.
