Definitions

• the present invention relates to the technical field of security elements for securities documents, such as fiduciary documents or similar.
• “fiduciary document” means all documents such as banknotes, checks, bank cards, used to transmit a sum of money.
• “Assimilated document” means any document issued by an administration of the State to prove the identity of a person, his rights to drive a vehicle, such as in particular the identity card, the passport, driving license, etc. By this expression is also meant any document used to authenticate an object of value such as for example a label affixed to a luxury garment. We also hear any document used to authenticate the payment of a tax such as tax stamps.
• the complexity of producing such an element generally lies in a combination of printing techniques difficult to reproduce with consumer copying equipment (scanner, laser or color inkjet printers, etc.) and / or standard printing equipment.

• the first 22A and second 22B patterns are printed with an interferential optical interference iridescent ink.
• an iridescent ink of particular formulation printed in a transparent area of a substrate produces hue variations when the viewing conditions in transmission and reflection vary.
• This ink also known as pearl effect ink, incorporates, for example, pigments with small semi-transparent plates that reflect light. These small plates give depth and shine in ink.
• the size of the pigments makes it possible to vary the satin or scintillating effect of the ink. Thus, a satin effect is obtained with fine pigments and a flicker effect with coarse pigments.
• the pigments are based on mica and are prepared by grinding mica chips on which is deposited a metal layer such as for example titanium oxide or iron oxide.
• the color and the optical effect obtained depend in particular on the thickness of this layer.
