    摘要： A security element comprising a first and a second pattern PAT1 and PAT2 formed in or on a substrate, the first pattern PAT1 being formed by a first material INK1 applied to a first region of the substrate, the second pattern PAT2 being formed by a second material INK2 applied to a second region of the substrate, said first and second regions of the substrate overlapping, wherein - a part of the first pattern PAT1 overlaps with a part of said second pattern PAT2, - the first material INK1 comprises a first luminescent dye or pigment DYE1, which upon excitation by electromagnetic radiation falling within an excitation wavelength range λ1a of the first luminescent dye or pigment DYE1 is capable of emitting electromagnetic radiation in at least one first emission wavelength range λ1e, and - the second material INK2 comprises a second luminescent dye or pigment DYE2, which upon excitation by electromagnetic radiation falling within an excitation wavelength range λ2a of the second luminescent dye or pigment DYE2 is capable of emitting electromagnetic radiation in at least one second emission wavelength range λ2e, and - said first emission wavelength range λ1e of the first luminescent dye or pigment DYE1 overlaps with the excitation wavelength range λ2a of the second luminescent dye or pigment DYE2, so that upon irradiation with electromagnetic radiation within the excitation wavelength range λ1a of the first luminescent dye or pigment DYE1 the second luminescent dye or pigment DYE2 is excited, in the area of overlap of the patterns, to emit electromagnetic radiation in the emission wavelength range λ2e.

    摘要： The present invention relates to markers for liquids that can be used to authenticate the origin and genuineness of a liquid, preferably a bulk liquid such as fuel. For this purpose, the present invention teaches the use of a polymer capable of forming a semiconducting polymer particle (pdot) in the liquid in small amounts. The invention encompasses a liquid comprising a) a polymer that is capable of forming a semiconducting polymer particle (pdot), the concentration of the polymer being 10 ppm by weight or less, and b)an organic substance in an amount of 90% by weight or more. The invention furthermore envisages the use of such a polymer as an authenticating marker in a liquid, preferably a fuel, and a method for authenticating the genuineness and/or origin of a liquid comprising a polymer capable of forming a semiconducting polymer particle (pdot), comprising the steps i. concentrating, isolating and/or extracting the polymer capable of forming a semiconducting polymer particle (pdot); ii. aggregating the polymer or the polymer obtained in Step i. to form semiconducting polymer dots (pdots); iii. irradiating the formed pdots with electromagnetic radiation capable of exciting the pdots to emit electromagnetic radiation by fluorescence and/or phosphorescence, and iv. observing the electromagnetic radiation emitted in response to the exciting irradiation of step iii.
