    摘要: A security element for the identification and authentication of objects is disclosed. The element is connected by a self-adhesive label to an object. It has features that effectively prevent non-destructive detachment of the security element from an object. The security element has an optical code for identification. Furthermore, it is provided with random production-governed features by means of which authentication is made possible: upon irradiation with electromagnetic radiation, a scattering region of the security element brings about a characteristic scattering signal. The method of using the security element is disclosed for the identification and authentication of objects and also for protection against forgeries, and a method for the identification and authentication of objects on the basis of the security element.

    摘要: The present invention relates to a multi-stage membrane filtration process for reconcentrating the overspray from a one-component, aqueous coating composition containing high molecular weight components having a weight average molecular weight of at least 2000 and at least 5% by weight, based on the total weight of the organic components of the coating composition, of a low molecular weight component having a weight average molecular weight of less than 2000, that has been diluted with spray booth water from spray booths having wet flushing to form a booth/water overspray mixture bya) preconcentrating the booth water/overspray mixture in an ultrafiltration unit to obtain a first retentate containing high molecular weight components and a first permeant containing water and at least a portion of the low molecular weight components,b) treating said first permeant and the third permeant obtained in step c) below in a reverse osmosis unit to obtain a second permeant containing essentially pure water for recycle as booth water and a retentate containing low molecular weight components,c) treating said first and second retentates in a nanofiltration unit to obtain a third permeant containing water and a minor portion of low molecular weight components and a third retentate which largely corresponds in composition and concentration to said one-component, aqueous coating composition.
