Abstract
A hologram decal including a hologram layer having first and second surfaces, a first polymer layer secured to the first hologram surface, a second polymer layer secured to the second hologram surface, a pressure sensitive adhesive layer disposed on the non-hologram side of one of the first and second polymer layers, and a release liner covering said pressure sensitive adhesive layer, and techniques for making the hologram decal.
Claims8
A process for making a hologram decal comprising the steps of:
- recording a hologram in a hologram layer having a first surface in contact with a first substrate and a second surface in contact with a second substrate;
- removing the hologram layer and the first substrate from the second substrate such that the second surface of the hologram layer is uncovered;
- attaching to the second surface of the hologram layer a laminar structure comprised of a first polymer layer, a pressure sensitive adhesive layer, and a release liner such that (1) the pressure sensitive layer is between the first polymer layer and the release liner, and (2) the first polymer layer is adjacent the hologram layer;
- removing the first substrate from the hologram layer to uncover the first surface of the hologram layer;
- attaching a second polymer layer to the first surface of the hologram layer.
