    摘要: A security document (1) is provided having a substrate (4) and an integral security device (10) which includes an image layer (12) and a focussing layer (11). each formed from a radiation curable ink layer embossed with relief formations (13; 15). The first radiation curable layer embossed with relief formations (13) to form the image layer (12) is provided on a first surface of the document, and the second radiation curable layer (11) embossed with focussing element relief formations (15) is provided on a second surface of the document. The first and second surfaces are separated by a predetermined distance D to produce a visible optical effect when viewing the image layer (12) through the focussing layer (11). In preferred embodiments, at least one of the first and second radiation curable layers is embossed with diffractive relief structures and high refractive index or reflective coatings may be applied to the embossed relief formations in the image layer (12) and/or the focussing layer (11). The invention allows security devices to be integrated in a security document, such as a banknote, in a cost-effective manner, without substantially increasing the thickness of the document.

    摘要: A security document or device is provided which incorporates one or more optical components. Each component includes at least one orientating layer, preferably a photo-orientated polymer network (PPN), and at least one liquid crystal polymer (LCP) layer, and either or both of the orientating layers and LCP layers include a cross-linker to improve the robustness of the document or device without detracting from the desired optical properties. Such a document or device can be authenticated using an external polariser, or using a polariser integral to the document or device itself.
