Abstract: A method for producing pigments comprises the steps of creating a first layer on a substrate, structuring the first layer and detaching the pigments from the substrate. In the present case, the first layer is a crack-forming layer, so that the first layer is structured by the arising of cracks. Prior to detaching the pigments, a pigment layer is applied onto the first layer structured by the cracks.

Abstract: A process for producing pigments having a defined size and shape and also pigments produced by this process. The process has the steps: a) production of a three-dimensional surface structure on a substrate, with surface regions which are in each case partly bounded by a plurality of three-dimensional structural elements and are arranged in gaps being formed; b) application of a pigment material layer to the surface structure; c) detachment of the pigment material layer from the surface structure and production of pigments.

Abstract: A composite glass comprises two glass and/or plastic plates and an intermediate foil arranged between the glass and/or plastic plates. The composite glass, due to the intermediate foil, is configured differently in a side-dependent manner, by appearing to a viewer more transparent from an inner side than from an outer side. The composite glass, due to the intermediate foil, appears to the viewer different in a viewing angle-dependent manner from the outer side.

Abstract: 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.

Abstract: A flat security element has a main plane and microreflector arranged in a microreflector pattern and present at least one motif that, when the security element is tilted, has a motif effect that relates to the main plane. The microreflector pattern causes a first and a second motif effect, wherein the first motif effect occurs during a tilting movement about a primary axis, if the security element is at the same time oriented within a first tilting angle range about a secondary axis, and the second motif effect occurs during the tilting movement about the primary axis, if the security element is at the same time oriented within a second tilting angle range about the secondary axis.
