Abstract
A retroreflective article including a retroreflective element layer having an array of a large number of total internal reflective cube corner retroreflective elements, an optical property-adjusting layer partially provided on the back side of the retroreflective element layer, and an air layer on the back side of the optical property-adjusting layer. The retroreflective article exhibits optical properties suited for an intended use, such as a reflector of traffic or commercial signs, such as traffic signs, regulating signs, informative signs, and construction signs, or visible, laser or infrared light reflective sensors, by the presence of the optical property-adjusting layer with an adjusted hue or an adjusted area ratio. The retroreflective article can easily be produced at low cost and high efficiency by utilizing an existing retroreflective article.
