It is in the range of 100 μm. Here, when the refractive index is less than 2.0, when the water is submerged, the visibility is remarkably reduced. On the other hand, when it exceeds 2.5, there is a disadvantage that light is refracted too much, does not retroreflect well, and eventually has poor visibility. The method for measuring the refractive index of the glass beads is not particularly limited, and can be measured by, for example, an immersion method. With the immersion method, glass beads are submerged in liquids of various refractive indices, and light is applied to them to investigate whether or not the refractive index changes between the liquid and the glass beads. Is a method of measuring In Examples described later, measurement was performed according to this method.

If it exceeds 0 μm, the beads crystallize, become white turbid and lose transparency, and the reflex reflection decreases. The particle size of the glass beads can be adjusted by a mesh sieve (standard sieve). The particle size can be measured by using the mesh sieve or by a method using an electron micrograph. In the examples described below, the particle size was determined using a mesh sieve according to JIS-K3301 for glass beads.
