  • Latent-reactively glued TPU/PC layer materials
    Patent number: 8911851
    Abstract: A document (2) containing: electronic components (14) and/or diffractive security elements; at least one protective layer (4, 5) being arranged on one side or two protective layers (4, 5) being arranged on both sides of the electronic components (14) and/or of the diffractive security element, said protective layers being formed of a first base polymer, polymer layers (8, 9, 12, 13), being formed of a second base polymer being different from the first base polymer, into which the electronic components (14) and/or the diffractive security element with the protective layers (4, 5) are laminated; and adhesive layers with a latent-reactive adhesive (10, 11) being arranged at least between the polymer layers (8, 9, 12, 13) and the protective layers (4, 5), and wherein the core layer or protective layers are formed of a thermoplastic elastomer.
