Multi-layered solid plastic identity card comprising a laminate of different plastic layers which is particularly resistant to environmental influences and effects of daily use and has high durability. The use of plastics which are stable at high temperatures, such as PC (polycarbonate), for the card core (3) and the outer sheets (1) ensures the dimensional and temperature stability even under extreme environmental conditions and the use of intermediate layers (2) of a thermoplastic elastomer such as TPU (thermoplastic polyurethane) minimises the risk of the card breaking, since these layers absorb stresses and shearing forces and make the card flexible. <IMAGE> |
