A process for producing multilayered microparticles for marking and later identifying substances or objects of any desired type, even animals and plants, has the following steps: several marking layers are successively applied in the liquid state onto a web-shaped or sheet-shaped substrate, each layer being dried and/or hardened before the next marking layer is applied, until a stack of layers of the desired type and in the desired order is obtained; the substrate is separated from the stack of layers; and the stack of layers is crushed into multilayered microparticles without affecting the integrity of the series of marking layers. A first disclosed process is characterised in that the individual marking layers are applied by a printing process. Alternative processes are characterised in that the individual marking layers are applied by bronzing, by spray painting or by roll coating.

Ce procédé permet de produire des microparticules à couches multiples utiles pour marquer et identifier ultérieurement des substances ou des objets de tous types, même des animaux et des plantes. Le procédé comporte les étapes suivantes: on applique successivement sur un support en forme de bande ou de feuille plusieurs couches de marquage à l'état liquide qui sont ensuite séchées et/ou durcies avant que la prochaine couche de marquage ne soit appliquée, jusqu'à obtenir une série de couches d'identification d'un type voulu et empilées dans l'ordre voulu; le support est séparé des couches empilées; et les couches empilées sont broyées en microparticules à couches multiples sans affecter l'intégrité de la série de couches de marquage. Un premier procédé se caractérise en ce que les couches individuelles de marquage sont appliquées par un procédé d'impression. D'autres procédés décrits se caractérisent en ce que les couches individuelles de marquage sont appliquées par un procédé de bronzage, de peinture au pistolet ou d'enduction au rouleau.
