    摘要： A laminate includes a diffraction layer that is optically transmissive and includes a diffraction part with a plurality of diffraction units being repetition of a diffraction unit in a direction extending the diffraction layer, each diffraction unit including at least one diffraction element with a reflective diffraction grating; and an absorption layer that is optically transmissive with a plurality of absorption parts for at least part of visible light, the absorption layer facing the diffraction layer with light passing between the diffraction layer and the absorption layer. The laminate has an observation side opposite where the diffraction layer faces the absorption layer; the diffraction layer has a surface serving as a front surface opposite to the surface facing the absorption layer; and in plan view perpendicular to the front surface of the diffraction layer, each of the absorption parts aligns with one of the diffraction elements.

    摘要： The invention concerns a process for producing a film element having mutually registered metallic layers (11, 16) and a film element which can be produced by such a process. A first metallic layer (11) provided on a first surface of a flexible single-layer or multi-layer carrier film (10) and a masking layer (13) provided on the second surface of the carrier film (10), opposite to the first surface, are structured in accurate register relationship with each other by means of mutually synchronized structuring procedures. After structuring of the first metallic layer (11) and the masking layer (13) one or more further layers are applied to the first metallic layer (11). Applied to the one or more further layers (15) is a second metallic layer (16) to which a first photoactivatable layer (17) is applied. The first photoactivatable layer (17) is structured by means of trans-exposure through the masking layer (13), the first metallic layer, the one or more further layers and the second metallic layer (16) from the side of the masking layer (13) by means of electromagnetic radiation of a wavelength to which the first photoactivatable layer (17) is sensitive, or the first photoactivatable layer is exposed controlledly through the masking layer from the side of the film body that is opposite to the masking layer.

    摘要： The invention relates to a security document 10 and a method of making the security document 10. The security document 10 has an optically transmissive region with a first surface and a second surface on an opposite side to the first surface. On a portion of the first surface is a first opacifying layer 14, with an area B of the optically transmissive region not being covered by the first opacifying layer 14. Similarly, on a portion of the second surface is a second opacifying layer 16, with an area A of the optically transmissive region not being covered by the second opacifying layer 16. The uncovered area B of the first surface does not substantially overlap the uncovered area A of the second surface. Further, the uncovered area B of the first surface and uncovered area A of the second surface appear to be substantially contiguous when viewed in transmitted light.
