Abstract: The present disclosure generally relates to retroreflective sheeting including a topcoat and to methods of making such sheeting. In some embodiments, the retroreflective sheeting includes (1) a first major surface that is a structured surface having a structure imparted by a plurality of prismatic cube corner elements; (2) a second major surface opposite the first major surface, the second major surface being substantially planar and including a polycarbonate; and (3) a topcoat adjacent to at least a portion of the second major surface and the topcoat including a solvent-based composition.

Abstract: The present disclosure relates to the formation of high contrast, wavelength independent retroreflective sheeting made by including a light scattering material on at least a portion of the retroreflective sheeting. The light scattering material reduces the brightness of the retroreflective sheeting without substantially changing the appearance of the retroreflective sheeting when viewed under scattered light.

Abstract translation: 本公开内容涉及形成通过在至少一部分回射片材上包括光散射材料制成的高对比度，波长无关的回射片材。 光散射材料在散射光下观察时，基本上不会改变回射片的外观，降低了反光片的亮度。
