PROBLEM TO BE SOLVED: To provide paint for a road surface line sign that is free of problems associated with smoothness of projection part surfaces and sticking properties of glass beads as well as shape maintaining properties of a projection part when the road surface line sign comprising beltlike lines having plane parts and projection parts (projection streaks) is formed by a slitter (slitter type coating machine).SOLUTION: Paint for a road surface line sign contains a thermoplastic binder, an extender, a plasticizer, coloring pigment, and the glass beads as essential components, and also contains a thixotropy-imparting agent as a combined material of bentonite and oxidation PE wax in addition to the essential components. The paint contains 0.1-0.55% of the former and 0.17-0.33% of the latter for the total amount thereof. The paint is suitable for construction of the line sign comprising beltlike lines, having plane parts 11 and projection streaks (projection part) 13 on a road surface 17, on the road surface using a slitter type coating device 21. |
