Patent

CA 2663270

The present invention relates to a method for marking at least one material comprising a non-organic matrix, characterised in that it comprises at least one step that involves incorporating in said material during the production thereof at least one compound containing at least one luminescent lanthanide in a concentration such that said compound in said material can be detected under UV radiation, wherein said compound is a co-ordination polymer in the form of a crystallite obtained by reacting at least one luminescent lanthanide ion with at least one unsaturated organic binder.

L'invention concerne un procédé de marquage d'au moins un matériau comprenant une matrice minérale caractérisé en ce qu'il comprend au moins une étape consistant à y incorporer au cours de sa fabrication au moins un composé à base d'au moins un lanthanide luminescent selon une concentration rendant ce composé détectable sous irradiation UV dans ledit matériau, ledit composé étant un polymère de coordination se présentant sous la forme d'une cristallite obtenue par réaction d'au moins un ion lanthanide luminescent avec au moins un ligand organique insaturé.
