摘要： The invention relates to a mask exposure method comprising the following steps: —the providing of a carrier substrate; the print application of a radiation-crosslinkable washable dye layer to the full area of the carrier substrate; —the exposure of the radiation-crosslinkable washable dye layer in defined regions to radiation by means of a radiation mask, such that the washable dye is cured in the defined regions; —the applying of a metallization over the full area; —the removing of the non-radiation-exposed washable dye outside the defined regions together with the metal present thereon with the aid of a solvent, such that the resultant carrier substrate has cured washable dye with metal applied thereto only in defined regions.

摘要： A security element (1) for a security paper, value document or the like, having a carrier (8) which has an areal region (3) which is divided into a multiplicity of pixels (4) which respectively includes at least one optically active facet (5), whereby the majority of the pixels (4) respectively have several of the optically active facets (5) of identical orientation per pixel (4), and the facets (5) are so oriented that the areal region (3) is perceptible to a viewer as an area that protrudes and/or recedes relative to its actual spatial form.

摘要： A security element for securing security papers, value documents and other data carriers, having a lenticular image that, from different viewing directions, displays at least two different appearances. The lenticular image includes a lens grid composed of a plurality of microlenses and a radiation-sensitive motif layer arranged spaced apart from the lens grid. The radiation-sensitive motif layer includes, produced by the action of radiation, a plurality of transparency regions that are each arranged in perfect register with the microlenses of the lens grid. Outside the transparency regions produced by the action of radiation, the radiation-sensitive motif layer is opaque and patterned in the form of a first motif such that, when the security element is viewed through the lens grid from a first viewing direction, the first motif is visible as the first appearance.

摘要： A method includes using a lenticular image having a lens grid composed of a plurality of microlenses and a metallic motif layer arranged spaced apart from the lens grid; the refractive effect of the microlenses defines a focal plane and the metallic motif layer being arranged substantially in the focal plane; a line width is chosen for the demetalized sub-regions to be produced in the metallic motif layer; a marking laser source having a laser wavelength λ is selected such that the resolving power D(λ) of the microlenses of the lenticular image at the selected laser wavelength λ substantially corresponds to the line width of the demetalized sub-regions to be produced; and the metallic motif layer is impinged on through the microlenses with laser radiation of the marking laser source to produce demetalized sub-regions in the metallic motif layer.

摘要： A method for manufacturing an optically variable security element, so that for a viewer of the security element, a first color impression is created through the combination of at least the color effects of a first embossing lacquer layer and the coating, and a second, different color impression is created through the combination of the color effects of at least the first embossing lacquer layer, a second embossing lacquer layer and a coating.

摘要： An optically variable security element has a multicolored, reflective areal region including a first relief structure disposed at a higher level than a second relief structure. The first relief structure has a first ink coating and the second relief structure has a second, different ink coating. The two relief structures overlap in an overlap region. The first ink coating of the first relief structure is disposed at a higher level in the overlap region and has at least one recess the dimension of which is more than 140 μm. The first ink coating comprises an edge region adjoining the recess, and as a bicolor register feature the first relief structure lets the edge region of the first ink coating appear with a first color impression and the second relief structure through the recess lets the second ink coating appear with a second, different color impression in mutual register.

摘要： An optically variable security element wherein the areal expansion whereof defines a z direction standing perpendicularly thereon, and has a multicolored, reflective areal region. The areal region includes two relief structures arranged at different height levels in the z direction. The relief structures are each supplied with an ink coating which produce a different color impression. The ink coating of the relief structure disposed at a higher level is configured in the feature region as a regular or irregular grid with grid elements and grid spaces. The dimensions of the grid elements and/or grid spaces are below 140 μm at least in one direction, so that, in the feature region, for a viewer from at least one viewing angle, the ink coating of the relief structure disposed at a lower level is visible through the grid spaces of the ink coating of the relief structure disposed at a higher level.
