Abstract: A method for producing a multilayer body, with the steps: a) providing a first printed layer; b) partially applying a second printed layer to the first printed layer; c) structuring the first printed layer using the second printed layer as a mask. A multilayer body obtainable in this way and a security document with such a multilayer body.

Abstract: A method for producing a multi-layer body, in particular a security element, in which a partial first layer or partial first layer system is produced on a substrate, wherein the partial first layer or partial first layer system is present in a first partial area and not in a second partial area. Subsequently, a partial second layer or partial second layer system is produced, wherein the partial second layer or partial second layer system is present in a third partial area and not in a fourth partial area, and wherein the third partial area overlaps with the first and second partial areas. Finally, the partial first layer or partial first layer system is structured as a mask using the partial second layer or partial second layer system.

Abstract: A method for forming a volume hologram film having security elements which are formed as a transfer section of the volume hologram film is described, wherein the volume hologram film has n volume hologram layers arranged one over another. The production of the volume hologram film is carried out in a roll-to-roll method with the following method steps: a) providing a carrier film from a supply roll; b) applying an i-th photopolymer layer to the carrier film; c) forming an i-th volume hologram in the photopolymer layer; d) forming an i-th volume hologram layer by curing the i-th photopolymer layer; e) repeating process steps b) to e) n?1 times; f) applying an adhesive layer to the background layer; g) winding the volume hologram film onto a take-up roll.

Abstract: For an electrical plug connector for printed circuit boards, in particular rear-wall plug connectors with a frame-shaped insulating body in which pin-shaped contact elements are disposed in columns and rows, the insulating body being constructed for receiving multi-row spring strips, it is proposed that an adapter, in which a 3-row spring strip can be inserted, be latched into the insulating body.

Abstract: For a unilaterally contacting contact spring for electric connectors, it is proposed to influence the contact force of the spring limb by means of an adjusting spring which acts upon the spring limb. As a result, a high contact pressure is already achieved upon slight deflection of the spring limb and, upon maximum deflection, the characteristic curve of the spring presents a flatter shape so that the contact force does not assume excessively high values.
