Abstract: A method of producing a light reflective material in which a mixture of particles and a carrier material is applied to a substrate. Each particle comprises a body of transparent or translucent material and a coating on part of the surface of the body. The coating is light reflective and comprises a material having magnetic or electrical properties. An adhesive is contained in the carrier material or in the coating. A magnetic or electrical field is applied to the mixture and causes the particles to move towards a predetermined orientation relative to the substrate. This orientation is normally one in which an uncoated part of each particle faces outwardly away from the substrate, but in the case of a transparent or translucent substrate the uncoated part may face inwardly towards the substrate. When the particles are correctly oriented, the adhesive is activated to secure them to the substrate.

Abstract: Coating compositions for coating fabrics to make them brightly retroreflective at nighttime while making a minimal change in their ordinary daylight appearance, The compositions comprise a dilute coating vehicle, preferably an aqueous emulsion of an acrylic-based polymer, and transparent retroreflective microspheres dispersed in the vehicle. The vehicle is diluted with at least40 volume-percent of a volatile constituent, and the microspheres account for about one-third or less of the volume of the nonvolatile portion of the composition. When the composition is coated onto a fabric (10) the retroreflective microspheres (12) become scattered over the surface of the fabric at low density, often in recesses (13) in the fabric surface, and become adhered to the fabric by a binder material (11) in the coating vehicle.
