Beschreibung
Zusammenfassung:	This invention provides a retroreflective sheeting which at least comprises a printed image-incorporated retroreflective sheeting and an optical element array sheet in which a large number of light-transmissive optical elements are regularly disposed at least at a fixed location; more particularly a printed image-incorporated retroreflective sheeting which reveals a stereoscopic image when the printed image is seen through a lenticular lens sheet or a convex lens array sheet; and a reflective sheeting which uses the stereoscopic image for tamper prevention.
