ABSTRACT:
A light-polarizing element for use in a security document to permit authentication of the security document includes an intermediate layer of water-absorbing polymer material laminated between two outer layers of transparent material. The intermediate layer contains polarizing crystals that are absorbed in the intermediate layer and that are oriented in a predetermined direction through mechanical stretching. The two outer layers are sealed to one another in a liquid-tight manner along their longitudinal edges.
