The invention relates to a process for identifying and authenticating an object. The object includes an identifier which has a code region and a scattering region and is irradiated with electromagnetic radiation for identifying and/or authenticating the object, in such a manner that the electromagnetic radiation reflected by the code region is used for identifying the object and the electromagnetic radiation reflected by the scattering region is used for authenticating the object. In addition, the invention relates to a device for the parallel identification and authentication of an object.

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 by
