Abstract

L’invention vise à fournir des marqueurs pour l'identification et/ou l'authentification d’objets, notamment d'objets de valeur, et plus précisément des marqueurs, stables, efficaces, facilement synthétisables, économiques, infalsifiables et offrant des possibilités de codages multiples et complexes. L’invention concerne des particules (P) en particulier adaptées au marquage, à l'identification et/ou à l'authentification d'objets, notamment d'objets de valeur :- à base d’au moins un polymère porteur de groupements chélatants,- dont la plus grande dimension est comprise entre 0,1 et 1000 µm, de préférence entre 1 à 500 µm, encore plus préférentiellement entre 1 à 50 µm, et- auxquelles sont liés au moins un élément minéral de marquage (M) et éventuellement au moins un élément organique de marquage (O); au moins une partie de cet (ces) élément(s) minéral(aux) (M) de marquage étant chélatée par le polymère. L'invention concerne également une poudre, une suspension ou une composition comprenant ces particules P, ainsi qu'un procédé de fabrication de celles-ci.
