摘要： A retroreflective article that has a layer of optical elements and a multilayer reflective coating disposed on the optical elements. The reflective coating reflects light back into the optical elements so that it can be returned toward the light source. The multilayer reflective coating has multiple polymer layers and has layers that possess different refractive indices.

摘要： A portable system and method for printing variable information indicia on a reflective sign comprises providing a first polymeric sign component having a surface suitable for receiving a printed image. A definition of an image to be printed on the first sign component is provided to a portable computer. Indicia in the form of images is then rapidly transferred to the surface of the first sign component.

摘要： Cellular retroreflective sheeting, which comprises a base layer of retroreflective elements and a transparent cover film supported in spaced relation away from the base layer by a network of narrow intersecting bonds that form hermetically sealed cells within which retroreflective elements are isolated from retroreflective elements of different cells, is given greater durability by use of bonds that are cured in situ after they have been thermoformed into sealing contact between the cover film and base layer.
