Abstract:
A holographic element comprising:a paper support having two flat surfaces, one of said surfaces having: an adhesive layer, and; a metallized holographic image wherein said metallized holographic image comprises at least two holograms therein, one of said holograms being visible by non-coherent light and the other of said holograms being visible by coherent light, and wherein said metallized holographic image is obtained from a plurality of holographic images formed on a photosensitive element coated on a polymeric support by masking part of said photosensitive element; forming a first holographic image viewable by non-coherent light on the un-masked part of said photosensitive element; removing said mask; forming a second holographic image viewable by coherent light on to the area of the photosensitive element that has been covered by said mask; and wherein said holographic images are then metallized and overcoated with an adhesive layer, and wherein said metallized holographic image is subsequently transferred to said paper support from said polymeric support by laminating the adhesive layer coated over said metallized holographic image to said paper support at a temperature of between 0 degrees C. and 150 degrees C. and a pressure of greater than 1 pound per square inch and subsequently delaminating said polymeric support from said paper support substantially transferring all of the metallized portion of the holographic image to said paper support and leaving the holographic image on the polymeric support suitable for reuse.
