The present invention relates to the use of non-deactivatable security compositions comprising the combination of at least two types of particles of oxide materials, where said particles have a different size and/or morphology, and where the inorganic oxide materials have at least one transition metal or one lanthanide element, and radiofrequency wave absorption properties. The invention also relates to security articles, documents or elements incorporating these compositions, as well as to a method and to a system for detection thereof.

Use of radiofrequency wave absorbing markets for the authentication of security documents

The present invention relates to the use of non deactivable security markers comprising the combination of at least two types of nanoparticles of materials presenting Raman effect, wherein said nanoparticles are in a dispersed state or is forming agglomerates of between 2 and 500 nanoparticles. The invention also relates to security documents, articles or elements incorporating these markers, as well as to a method and system for the detection thereof.

Use of Raman markers for authenticating security documents

The present invention relates to a new family of luminescent pigments consisting of a salt of two ruthenium(II) complex ions of opposite sign charges comprising N-chelating heterocyclic ligands and to their use in security applications to prevent counterfeiting. The invention also refers to ink compositions and to the security documents or secured goods comprising said luminescent pigments.
