  • Substrates
    Publication number: 20090029123
    Abstract: The invention relates to improvements in substrates and in particular to new substrates having magnetic and visual security features, which provide security against imitation. A security substrate comprising a transparent polymer carrier layer bearing indicia formed from a plurality of opaque and non-opaque regions and a clear and transparent magnetic layer supported by the carrier layer containing a distribution of particles of a soft magnetic material of a size and distributed in a concentration at which the magnetic layer remains clear and transparent.
