摘要： A method for producing a multilayer body, with the steps of: a) providing a substrate film with a replication layer; b) molding a surface relief appearing to the observer in the form of a three-dimensional free-form surface, which is formed in particular by structures with a lens-like design generating a magnifying, demagnifying or distorting effect, into a surface of the replication layer; c) applying a first metal layer to the surface of the replication layer forming the surface relief; d) wet-chemically applying an at least partially transparent spacer layer to the metal layer; e) applying a second metal layer to the spacer layer.

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： An optically variable element has first and second diffraction gratings which are high-frequency and therefore act reflectively into the zero diffraction order. Either a first color is generated by the first diffraction grating at a particular angle of rotation and a particular angle of illumination and simultaneously a second color, different from the first color, is generated by the second diffraction grating or a visible color is generated essentially only by the first diffraction grating at a first angle of rotation and a visible color is generated essentially only by the second diffraction grating at a second angle of rotation.

摘要： The invention relates to a method for producing a multilayer body (100, 200, 300, 400), as well as a multilayer body (100, 200, 300, 400) produced thereby. A single- or multi-layered first decorative ply (3) is applied to a carrier ply with a first (11) and a second (12) side. A metal layer (5) is applied to the side of the first decorative ply (3) facing away from the carrier ply and structured such that the metal layer (5) is provided with a first layer thickness in one or more first zones (8) and is provided with a second layer thickness different from the first layer thickness in one or more second zones (9), wherein in particular the second layer thickness is equal to zero. A single- or multi-layered second decorative ply (7) is applied to the side of the metal layer (5) facing away from the first decorative ply (3) and structured using the metal layer (5) as mask such that the first (3) or second (7) decorative ply is at least partially removed in the first (8) or second (9) zones.

摘要： A process for producing a multilayer body (100) is specified. In this process, an HRI layer (7) made of a material having a high refractive index is applied to at least part of the surface area of a substrate (4). At least one partial region (10) of the HRI layer (7) is then physically removed from the substrate (4) again by treatment with an alkaline solution. Additionally specified is a multilayer body (100) that can be obtained by such a process.

摘要： The invention relates to a film (1) and a process for its production. The film (1) comprises a light-permeable replication lacquer layer (2) with a diffractive relief structure (3) formed in a first side (21) of the replication lacquer layer (2), a light-permeable colour lacquer layer (4), formed only in areas, arranged on the relief structure (3), and a reflective layer (5), formed at least in areas, arranged on the first side (21) of the replication lacquer layer (2). In areas (63) of the film (1) where the colour lacquer layer (4) and the reflective layer (5) overlap, the colour lacquer layer (4) is arranged between the replication lacquer layer (2) and the reflective layer (5).
