Beschreibung
Zusammenfassung:	The present invention is directed to transparent articles including a microembossed image such as a hologram or diffraction grating, coated at least in-part, with a layer of material having a refractive index that differs from the refractive index of the transparent layer by about 0.2 units and can be prepared by solution coating techniques such as conventional printing, e.g., rotogravure.
