    Abstract: Techniques are described in which articles (e.g., security documents, traffic signage and personal protective equipment) are formed to include an infrared absorptive material. In some instances, the infrared absorptive material includes a reduced tungsten oxide, such as cesium tungsten oxide, calcium tungsten oxide, potassium tungsten oxide, or the like, and exposed to radiation such that one or more regions of the security document has a modified appearance, thereby providing a visual marking or information on the article. Example articles include at least one layer including a polymer and an infrared absorptive material including a reduced tungsten oxide. The layer includes a radiation-treated region that exhibits a first appearance under visible light and at least one non-radiation-treated region that exhibits a second, different appearance under visible light. The at least one radiation-treated region may be formed by exposing the at least one radiation-treated region to infrared light to change at least one property of the reduced tungsten oxide in the radiation-treated region compared to the reduced tungsten oxide in the non-radiation-treated region. The first appearance may be whiter than the second appearance.

    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: A prismatic retroreflective sheeting includes a structured layer that includes a plurality of cube corner elements including a reduced tungsten oxide, a radiation-treated region, and a non-radiation-treated region. The prismatic retroreflective sheeting includes also includes an information-containing layer above the structured layer. The information-containing layer includes at least one indicia defining an edge. The radiation-treated region of the structured layer is adjacent and below at least part of the edge of the at least one indicia.
