Abstract: An adhesive film that can be wound and stamped having an epoxy-based adhesive compound that can be activated thermally or by UV radiation, and a dye and/or pigment mixed into the adhesive compound for producing a first color change after the activation of the adhesive compound and a second color change after the curing of the adhesive compound.

Abstract: A cartridge covering element for sealing off a microfluidic cartridge comprising: at least one stratified adhesive mass, the stratified adhesive mass being UV-activatable to induce curing and being tacky at room temperature prior to and after activation until expiry of an open time.

Abstract: An adhesive tape 10 that can be wound and stamped for selective UV activation, comprising at least a first UV activatable adhesive compound 1 on an epoxide basis and a carrier 2, the carrier being UV intransparent, for providing selective UV activatability of the adhesive tape 10.

Abstract: A method for producing at least one patterned design having a plurality of pattern elements via a laser in a component that is at least partially transparent and is coated on a first surface. The component is coated on a first surface with at least one layer. The coated first surface of the component is surveyed with first co-ordinated. At least one patterned design is created with second coordinates. The second coordinates of the at least one patterned design are transformed into third coordinates. The coated first surface is irradiated with laser radiation via control coordinates. The laser radiation is measured on a second surface and the laser radiation received is compared via the sensor system with a reference value. The laser radiation is switched off when the reference value is reached.
