If it exceeds the weight%, the physical properties as a road marking material decrease,
The surface condition deteriorates, the adhesion and elongation to the road surface deteriorate, and the workability is impaired.The abrasion resistance of the road marking material decreases, and the opacity of the luminous pigment increases. It becomes difficult to color white or yellow, which is necessary as a marking material.

性道路標示材が得られる。The luminous road marking material of the present invention is characterized in that rubber or resin contains 10 to 45% by weight of a luminous pigment mainly composed of alumina having an average particle size of 40 to 400 μm. By specifying the type of the luminous pigment in this way, by specifying the average particle size and content, compared to the conventional luminous road marking material, the emission luminance is high,
A luminous road marking material which is excellent in visibility in a dark place and sufficiently satisfactory in practical use can be obtained.
