Abstract: A security element has at least two luminescent substances, in which the security element has a first and a second luminescent substance which have a substantially identical, joint emission band. The first or the second luminescent substance, or both luminescent substances, have at least one excitation band that leads to an emission at the joint emission band only in the case of the first or the second luminescent substance.

Abstract: The invention relates to a security element having at least two luminescent substances. The invention starts out from a security element having at least two luminescent substances, whereby the security element has a first and a second luminescent substance which have a substantially identical, joint emission band, whereby at least the first or the second luminescent substance, or both luminescent substances, have at least one excitation band that leads to an emission at the joint emission band only in the case of the first or the second luminescent substance.

Abstract: A sheet-shaped document of value (BN) has luminescent feature substances (20, 21). Preferably, one luminescent feature substance is present over the entire sheet-shaped document and has a low concentration, whereas a second luminescent feature substance is present at certain partial areas and has a higher concentration.

Abstract: The invention relates to a printed value document having at least one luminescent substance.

Abstract: The invention relates to a particle mixture and the stabilization of a homogeneous distribution of these particles in the mixture.

Abstract: The invention relates to a printed value document having at least one luminescent substance.

Abstract: The invention relates to a sheet-shaped document of value with luminescent feature substance and the manufacturing and checking of such a document of value. The invention starts out from the idea to provide a sheet-shaped document of value (BN) with a luminescent feature substance (20, 21), which is present all over with low concentration as well as at certain partial areas with higher concentration.

Abstract: The present invention relates to a data carrier which contains a novel pigment composition which is preferably applied to the data carrier in the form of a coding. The pigment composition comprises a dye and a solid resin. The dye is bound in the solid resin. The resin is produced as the reaction product obtained from an oligomerized polyisocyanate and a mixture of polyfunctional compounds with active hydrogen.
