Beschreibung
Zusammenfassung:	The invention relates to a method for marking a material, for example for purposes of authentication and/or traceability of said material, notably batches generated. The said marking method comprises: - a step of supplying a marking composition chosen among molecular tags, and - a step of incorporating said marking composition into said material. And, according to the invention, said marking composition comprises particles, advantageously remaining intact after incorporation in said material, which comprise: - a homogeneous porous matrix which comprises a plurality of pores, - an information support added to said homogeneous porous matrix, wherein said information support consists of a polymer comprising an information sequence, and - a particle surface having a coating with at least one fluidizing agent, suitable for promoting uniform dispersion of said particles within said material. L'invention concerne un procédé de marquage d'un matériau, par exemple à des fins d'authentification et/ou de traçabilité dudit matériau, notamment des lots générés. Ledit procédé de marquage comprend les étapes suivants : fourniture d'une composition de marquage choisie parmi les marqueurs moléculaires ; et incorporation de ladite composition de marquage dans ledit matériau. Et, selon l'invention, ladite composition de marquage comprend des particules, restant avantageusement intactes après incorporation dans ledit matériau, comprenant : une matrice poreuse homogène comprenant une pluralité de pores ; un support d'information ajouté à ladite matrice poreuse homogène, ledit support d'information consistantnt en un polymère comprenant une séquence d'information ; et une surface de particule présentant un revêtement avec au moins un agent fluidifiant, apte à favoriser une dispersion uniforme desdites particules au sein dudit matériau.
