Abstract
A foil/composite sheet which either (1) is suitable for use in directly forming a holographic image or diffraction grating image on a document substrate or (2) has a holographic image or diffraction grating image embossed in the composite sheet such that a party producing the final document may hot stamp a chip containing the holographic image directly on a substrate forming the major portion of the final document. The composite sheet is characterized in that it has a sufficient degree of transparency to permit a person viewing the holographic image or diffraction grating image of such composite sheet or chip therefrom affixed to a printed substrate to readily see the printing through the holographic image or diffraction grating image.
