The invention relates to electroluminescent arrangements (layers) containing special styrenes and to their use.

Electroluminescent arrangements and their use

The present invention relates to a sensor with a novel construction for a detection method of molecules labelled with fluorescent dye for detecting these dissolved substances or analytes by energy transfer with a simple fluorescence technique and increased sensitivity in the detection as well as versatile use for different tasks and the possibility of reproducible preparation of films bound to solid surfaces.

Optical biosensor and method of use

The process relates to the production of tamperproof documents by laminating an information carrier on one or both sides with foils which have an adhesive layer which is hardened by radical cross-linking.

Process for the production of documents which cannot be falsified

Process of using a semi-permeable membrane of acrylonitrile copolymers

The application relates to a process for the preparation of pigment concentrates, preferably pulverulent pigment concentrates, which is characterized in that the polymer present in an intimate mixture, free from non-ionic surface-active agents, of an aqueous pigment suspension and an aqueous latex of a polymer or polycondensate containing carboxyl groups, or an aqueous solution of a polymer or polycondensate containing carboxyl groups, is coagulated by adding an electrolyte, while thoroughly mixing intensively, and the coagulate containing the pigment is then separated off in a known manner and optionally dried. The pigment concentrates are suitable for pigmenting aqueous media and printing pastes for pigment printing of textiles.
