摘要:
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.
