The element (1) has an adhesive surface (3) that is coated with an adhesive film (4), where the adhesive comprises a powdery anti-blocking agent, and film-forming component. The anti-blocking agent is activated by heat and/or radiation and /or mechanical and/or solvent action. The agent is in a position after the activation to undergo a chemical reaction such as polymerization, polyaddition or polycondensation, with a component of the adhesive. The chemical reaction is triggered by radical or ionic or thermal or light radiation. An independent claim is also included for a method for manufacturing a security element. |
