Each transmission hologram optical element has a different light exit angle with respect to the center incidence angle of each diffraction incident angle at an arbitrary wavelength in the visible region, thereby widening the optical diffraction angle of the incident light and increasing the light utilization efficiency. It is possible to optimally set the distance between the color modulation elements of the optical modulation element in view of the utilization efficiency.

Holographic document and method for forming

A holographic article and method for forming permits the party producing the final document to print the holographic image directly on the final document thereby permitting such party to retain and maintain control of its own embossing shim on which the hologram has been formed and which is utilized for embossing the holographic image on the document. A film upon which a holographic image can be directly stamped upon the final document includes a layer of metal having a thickness in the range of 20 millimicrons to 100 millimicrons, a lacquer coating having a thickness in the range of 0.5 microns to 3 microns and a heat activatible adhesive. The metal layer lacquer coating and heat activatible adhesive are caused to be adhered to the substrate forming the final document during a stamping operation which releases said metal layer, lacquer coating and heat activatible adhesive from a plastic carrier film to which had initially been applied.
