<p>The present invention is directed to transparent articles including a microembossed image (3) such as a hologram or a diffraction grating, coated at least in-part, with a layer (4) 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.</p> |
