Abstract: An antimicrobial article includes a supporting layer and an antimicrobial layer. The antimicrobial layer has a first major surface at least partially formed by a plurality of particles and a second major surface coupled to the supporting layer. Each particle of the plurality of particles is formed by a bead of nonconductive material. A first set of the particles include beads coated by a first conductive material.

Abstract: Retroreflective articles include a layer of optical elements, the layer of optical elements being divided into at least a first segment (110) and second segment (120), and a bead bond layer (170) containing a colorant. The optical elements are partially embedded in the bead bond layer. The optical elements include transparent microspheres (140), a transparent polymeric layer (180), and at least one reflective layer. In the first segment of optical elements, the reflective layer is a dielectric reflective layer (150), and in the second segment of optical elements, the reflective layer is a reflective metallic layer (160). The retroreflective articles have improved wash durability.

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.
