    Abstract: The present disclosure provides a retroreflective article. The retroreflective article includes a retroreflective layer including a number of cube corner elements that collectively form a structured surface that is opposite a major surface, and a conformal wavelength-selective radiation absorbing coating layer adjacent to the structured surface. The present disclosure also provides a method of making a retroreflective article. The method includes obtaining a retroreflective layer, and forming a conformal wavelength-selective radiation absorbing coating layer on the retroreflective layer by applying a first material having a first binding group to the structured surface, and applying a second material having a second binding group to the first material. The conformal wavelength-selective radiation absorbing coating layer absorbs radiation of at least one selected wavelength and can impart color (or absorption of at least one wavelength outside of the colored wavelength range) to retroreflective light of the retroreflective article.

    Abstract: An exposed lens retroreflective article (100), transfer articles comprising same, and methods of making same. The retroreflective article can include a binder layer (114); a layer of transparent microspheres (108) partially embedded in the binder layer; and reflective layer (110) disposed between the binder layer and the microspheres. The reflective layer (110) can include a dielectric mirror, which can include a first stack (115) and a second stack (111) positioned in planar contact with the first stack, wherein each of the first stack and the second stack comprises at least one bilayer (119), wherein each bilayer comprises a first material with a first bonding group and a second material with a complementary second bonding group. The transfer article can include the retroreflective article and a carrier web. The method can include partially embedding transparent microspheres in a carrier web; applying the reflective layer to the microspheres, and applying a binder layer composition to the reflective layer.

    Abstract: An optical system includes an optical film curved about a first axis and a light control film curved about the first axis. The light control film can be disposed between a light source and the optical film. The optical film includes a microstructured first major surface and an opposing second major surface. The microstructured first major surface defines a linear Fresnel lens including a plurality of Fresnel elements extending longitudinally along the first axis. The first major surface of the optical film faces the light control film. The light control film can include a plurality of alternating optically transmissive and optically absorptive regions extending longitudinally along the first axis such that in a cross-section orthogonal to the first axis, for at least a majority of the optically transmissive regions, a centerline between adjacent optically absorptive regions is substantially normal to a major surface of the light control film.
