Abstract: The present invention relates to an application control composition comprising an indicator, wherein the indicator is modifiable and comprises at least one organic compound having a conjugated binding system, an organometallic compound or an inorganic compound. It further relates to an application control method and to the use of the composition according to the invention.

Abstract: The present invention relates to an article comprising fluorescence marker particles, wherein the fluorescence marker particles are distributed throughout the volume of the article or in a portion of the volume of the article and the fluorescence marker particles are present in a random distribution; the volume in which the fluorescence marker particles are distributed comprises a sub-volume; the sub-volume contains at least a portion of the fluorescence marker particles; the sub-volume is at least partially permeable to electromagnetic radiation having a wavelength in the visible range and/or in the near infrared range and/or in the UVA range; and/or a portion of the surface of the sub-volume is identical to a portion of the surface of the article; and a method of identifying it.

Abstract: The invention relates to a method for identifying pledged property, comprising the steps of: providing an apparatus, comprising: a guide tube in a substantially erect position, comprising an inlet and an outlet; and means for analysing the dynamic luminescence behaviour of a luminescent substance; wherein the means for analysing the dynamic luminescence behaviour of the luminescent substance are disposed so as to analyse the dynamic luminescence behaviour of the luminescent substance in the guide tube, even if said luminescent substance is in motion; introducing a pledged property containing the luminescent substance into the guide tube through the inlet; analysing the dynamic luminescence behaviour of the luminescent substance contained in the pledged property using the means for analysing the dynamic luminescence behaviour of the luminescent substance; and classifying the pledged property according to the result of the analysis.

Abstract: The present invention relates to a method of identifying and/or distinguishing materials by means of luminescence, wherein at least one luminescent substance is incorporated into the material and/or applied onto the material and the luminescence behaviour of the substance is analysed after excitation by means of radiation, and the use thereof for identifying and/or sorting and/or recycling and/or authenticating and/or performing a quality check and/or formulation check on materials.

Abstract: The present invention relates to a material, preferably a plastic material, comprising foreign substances, characterised in that the material further comprises fluorescent compounds, and a process for sorting a mixture of materials.

Abstract: The present invention relates to a workpiece which, on its surface, displays a depression having an opening width of at least 0.2 mm and in which depression a carrier material which is connected in a substantially inseparable manner to the workpiece and contains a characteristic marking material for the workpiece is disposed; and to a method for manufacturing the same and to a method for authentication and/or identification of the workpiece.

Abstract: The present invention relates to a method of authenticating and/or identifying an article containing a chemical marking agent, which is substantially inseparably enclosed in a marker as a carrier and contains selected chemical elements and/or compounds in the form of marker elements, in concentrations based on a predetermined encryption code, which method comprises the steps of: i) qualitatively and/or quantitatively identifying the marker elements of the chemical marking agent, and ii) comparing the values identified in step (i) with the predetermined encryption code.
