A process for making a hologram decal comprising the steps of:
- recording a hologram in a hologram layer having a first surface and a second surface;
- attaching to the first surface of the hologram layer a laminar structure comprised of a pressure sensitive adhesive layer, and a release liner such that the pressure sensitive layer is against the first surface of the hologram layer;
- and
- applying a transparent coating to the second surface of the hologram layer.
