ABSTRACT:
A prismatic retroreflective article and a method for making same. The retroreflective article can include a transparent polymeric body portion, an optical layer coupled to the body portion, and an image layer coupled to the body portion opposite the optical layer. The image layer can define imaged portions and non-imaged portions of the prismatic retroreflective article. The image layer can include cross-links formed between a polymer resin having hydroxyl functional groups and a cross-linking agent having isocyanate functional groups. The image layer can have a percent elongation of at least 80 percent and less than 200 percent. The method can include printing or coating an image layer onto to the body portion of the retroreflective sheeting opposite the optical layer, and cross-linking the image layer to form cross-links between the hydroxyl functional groups of the polymer resin and the isocyanate functional groups of the cross-linking agent.
