Abstract
The invention relates to a fluorescing covering for roads, parking places, etc. which fluoresces when being illuminated with ultraviolet light. In addition to the fluorescing agent, the covering comprises a colouring pigment or a soluble colorant which filtrates the fluorescing light and dissipates only light having a desired wavelength. This colouring pigment or colorant also reflects light having a desired wavelength and absorbs light having a non-desired wavelength also from daylight or some other conventional light source.
