Abstract
Process for labelling a material based on at least one organic thermoplastic or thermosetting polymer matrix comprising a step that consists in incorporating therein, by dispersion during its manufacture or its formation, at least one compound based on at least one photoluminescent rare earth in a concentration that renders this compound detectable under UV irradiation, said compound being a coordination polymer that is in the form of a crystallite obtained by reaction of at least one photoluminescent rare-earth ion with at least one unsaturated organic ligand.
Claims21
Process for labeling a material based on at least one organic thermoplastic or thermosetting polymer matrix including a step consisting of incorporating, by dispersion during the production or shaping thereof, at least one compound based on at least one photoluminescent rare earth element according to a concentration making said compound detectable under UV irradiation, in which said compound is a coordination polymer in the form of a crystallite obtained by reacting at least one photoluminescent rare earth ion with at least one unsaturated organic ligand.
