Abstract

Articles that include at least one application layer; at least one bead bond layer (10); a layer of optical elements (20) that are partially embedded in the at least one bead bond layer (10); and at least one reflective layer (30) that is located functionally between the layer of optical elements (20) and the bead bond layer (10), wherein the at least one bead bond layer (10), the at least one application layer, or both comprise a cured product of an adhesive compositions that include polymerized units of one or more (meth)acrylate ester monomers derived from an alcohol containing 1 to 14 carbon atoms; at least one of urethane acrylate polymer or at least one acrylic copolymer; and at least one initiator.
