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.

Procédé de marquage d'un matériau à base d'au moins une matrice organique polymérique thermoplastique ou thermodurcissable comprenant une étape consistant à y incorporer par dispersion au cours de sa fabrication ou de sa mise en forme au moins un composé à base d'au moins une terre rare photoluminescente selon une concentration rendant ce composé détectable sous irradiation UV, ledit composé étant un polymère de coordination se présentant sous la forme d'une cristallite obtenue par réaction d'au moins un ion de terre rare photoluminescente avec au moins un ligand organique insaturé.
