Abstract
An ID document comprises a receiving substrate in or on which an ink that is fluorescent under UV-A lighting is locally deposited, and a multilayer optical security component attached to a substrate. The optical component comprises a structurable layer and a reflective dielectric layer discontinuously deposited on the structurable layer in the plane of the component so as to produce patterns. The reflective dielectric layer has a relative transmission of at most 40% in the UV-B or UV-C range. The optical component also include an assembly of at least one layer including pigments that are fluorescent when energized by UV-B or UV-C. These are deposited on the reflective dielectric layer in a uniform or discontinuous manner in the plane of the optical component.
