る。2. Description of the Related Art Paints used for marking roads, such as lane markings and road markings, are different from ordinary paints in that they have good adhesion to the road surface,
In addition to being excellent in properties such as abrasion resistance and water resistance, it is required to have excellent visibility at night or in bad weather such as rainfall and fog. Therefore, conventionally, attempts have been made to increase the visibility of road surface display at night by attaching transparent beads such as glass beads to the surface of a coating film and reflecting the transparent beads exposed on the surface of the coating film.

At night when the surface is covered with a water film or fog is generated and the light from the streetlight or the headlight of the vehicle does not reach sufficiently, the method of attaching the transparent beads described above In some cases, the visibility of the road surface display cannot be improved.

Therefore, there is also a problem that the visibility of the road surface display decreases with time, and the durability of the road surface display decreases.

JP-A-8-226109), or a transparent resin containing a fluorescent dye, in which a carrier composed of porous alumina particles is impregnated with a fluorescent agent. A method is considered in which fluorescent beads and fluorescent powder (see JP-A-6-228321 and JP-A-6-228470) whose surfaces are coated are mixed into a road surface paint.

The road surface display emits fluorescent light due to light from the street lamps or the like, and high visibility can be exhibited. However, in a situation where the amount of light from a streetlight or a headlight of a vehicle is insufficient, such as during bad weather such as rainfall or fog, visibility of road surface display cannot be improved. In addition, since no fluorescent light is emitted in a state where light is not irradiated, visibility at night or in bad weather cannot be improved.

When the light-storing pigment is left in a state of being shielded from light for 10 minutes, the afterglow luminance of the luminous pigment is 600 mcd / m 2 or more after 10 minutes from the light-shielding, and
It is not less than 5 mcd / m 2 after a lapse of time.

Therefore, by using the road surface display paint of the present invention, a road surface display exhibiting excellent visibility even at night or in bad weather can be produced. In the luminous pigment used in the present invention, the brightness at the time of irradiating light under the above-described conditions and then 10 minutes after shading is preferably 800 mcd / m 2 or more, more preferably 1000 mcd / m 2 or more.

If the amount of the luminous pigment is less than the above range, visibility at night or in bad weather becomes insufficient, which is not preferable. On the other hand, if the phosphorescent pigment is blended beyond the above range, the visibility is not improved and the cost is rather increased.

In addition, the resin is required to have sufficient transparency to exhibit light emission by a luminous pigment and color development by a color pigment described later. As such a thermoplastic resin, for example, acrylic resin, alkyd resin, petroleum resin, rosin resin and the like can be used.
