Abstract
A security object has a substrate (1) carrying a first motif (6) and mutually aligned thereto a second motif (7). The first motif (6) is formed by a volume hologram (8) and visible under a given viewing condition only. The second motif (7) can e.g. be a dye, a surface hologram, a perforation or any other non-variable or optically variable device. The first and the second motif (6, 7) combine to form a third motif, e.g. a legible text. The combination of the first motif (6) formed by a volume hologram (8) with the second motif provides an increased level of security

An anti-counterfeit security object comprising
- a substrate,
- a volume hologram arranged on or in the substrate,
- a first motif stored in said volume hologram and visible under a given viewing condition only, and
- a second motif stored outside said volume hologram and arranged in alignment with said first motif,
- wherein, under said viewing condition, said first and said second motif combine to a third motif.
An anti-counterfeit security object comprising
- a substrate
- a volume hologram arranged on or in the substrate
- a first motif stored in said volume hologram and visible under a given viewing condition only, and
- a second motif stored outside said volume hologram and arranged in alignment with said first motif,
- wherein, under said viewing condition, said first and said second motif combine to a third motif, and
- wherein said second motif is at least partially formed by an optically variable device.
An anti-counterfeit security object comprising
- a substrate,
- a volume hologram arranged on or in the substrate
- a first motif stored in said volume hologram and visible under a given viewing condition only, and
- a second motif stored outside said volume hologram and arranged in alignment with said first motif,
- wherein under said viewing condition, said first and said second motif combine to a third motif, and
- wherein said second motif is at least partially formed by holes extending through said substrate.
