Abstract:
The invention relates to a security feature for safeguarding value documents, comprising particles which are composed of at least two different, spatially separate solid homogeneous phases, wherein each of the phases is detectable and identifiable in a spatially resolved manner by means of a spatially resolving analytical method that is adapted for resolving down to the single-particle level.
