COMPOSITE REFLECTIVE ELEMENT FOR USE IN A ROAD-SURFACE MARKING MATERIAL, AND ROAD-SURFACE MARKING MATERIAL CONTAINING SAID COMPOSITE REFLECTIVE ELEMENT

摘要

Provided is a composite reflective element for use in a road-surface marking material. Said composite reflective element is highly resistant to heat, solvents, and hot water and has excellent binder adhesiveness, retroreflectivity, and visibility. The composite reflective element is characterized in that glass beads with an index of refraction between 1.5 and 2.8 and a mean diameter between 10 µm and 500 µm are affixed to the surface of a core material by means of an inorganic binder.
