A fluorescing coating which fluoresces when illuminated with light within the ultraviolet wavelength range. The coating is intended primarily for road markings of different kinds and includes material (4;5) with pigment for emitting colour when illuminated with light within the visible wavelength range and material which fluoresces when illuminated with light within the ultraviolet wavelength range. The coating further includes a binder (3). The invention is characterized in that the material which fluoresces when illuminated with light within the ultraviolet wavelength range consists of glass spheres (2) or glass pieces produced from a glass mass which has been doped with a dope additive such as to cause the glass in the glass spheres or glass pieces to fluoresce when illuminated with ultraviolet light. It is suggested that Figure 1 is published together with the abstract. <IMAGE> |
