ABSTRACT:
The holograph assembly has first and second hydrophobic substrates layers (14, 12) which carry therebetween a water absorbent layer (16). The holographic image layer (18) is protected against moisture from that side because the water absorbent layer acts as a sponge for the moisture diffusing through the first substrate (14). The upper side of the image layer is protected by first and second cover layers (20, 22) and second water absorbent cover layer (24), all of which must be transparent to view the holographic image. An adhesive may be applied between layers.
