LUMINESCENT ROAD SIGN

摘要

Road signs having a front face with directional indicia or other informational indicia thereon are provided with a photoluminescent composition containing rare earth materials. The photoluminescent composition is applied to at least a portion of the area of the front face of the road signs. In a preferred embodiment, the composition containing the rare earth materials is applied by silk screening. A clear coat composition is applied over the previously applied photoluminescent composition to discourage wearing and fading of the rare earth material. In at least one preferred embodiment, the front face of the road signs includes a reflective material that meets Federal Department of Transportation specification requirements, and the rare earth material composition is silk screened on the surface of the reflective material.
