Abstract:
A transfer article, a retroreflective article and methods of making the same. The transfer article can include an overlay. The retroreflective article can include an optical layer and an overlay. The optical layer can include a front surface and a rear surface, and can include retroreflective optical elements. The overlay can include a front surface and a rear surface adapted to be coupled to the front surface of a substrate, such as the optical layer. The overlay can further include a graphic, such that the graphic is buried with respect to the front surface of the overlay. A method of making the retroreflective article can include applying a graphic to the rear surface of the overlay, and coupling the overlay bearing the graphic to the front surface of a substrate, such as the optical layer.
