Title:
ROAD SURFACE LINE SIGN AND PAINT FOR ROAD SURFACE LINE SIGN
Document Type and Number:
Japanese Patent JP2015148114
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a road surface line sign that can easily make large a difference in reflectivity intensity between a white line (road surface line sign) or the like and a road surface at a scanning angle of a detection beam of a laser radar.SOLUTION: There is provided a road surface line sign that has one or a plurality of beltlike lines 15 to be detected by a laser radar formed of melting type paint, and also has glass beads scattered and fixed to coating films of the beltlike lines. The melting type paint essentially includes a thermoplastic binder, an extender, a plasticizer, coloring pigment, and the glass beads. The glass beads are formed of or principally of beads having a high refractive index (of, for example, 1.6 or larger) and a large diameter (of, for example, 500 μm or larger in median grain size).
