Abstract
A water based luminescent highway or roadway paint composition that contains a fine powdered luminescent substance which does not require an organic solvent, a colored paint dispersion, and a polyurethane resin which is water compatible and which imparts an extended surface life under normal traffic conditions. The luminescent substance may be either a phosphorescent material or a combination of a phosphorescent and a fluorescent material. When the fluorescent material is present in the luminescent substance a daytime luminescence or reflectivity or coloration is produced in addition to the phosphorescence produced at night when light (head lights of an automobile) shine on the paint composition marking the median highway stripe or the highway edges.
