ABSTRACT:
A color agent for a road marking material comprising composite particles having an average particle diameter of 0.01 to 10.0 μm, said composite particles comprising: inorganic particles; a gluing agent coating layer formed on surface of said inorganic particle; and an organic pigment coat formed onto said gluing agent coating layer in an amount of from 1 to 500 parts by weight based on 100 parts by weight of said inorganic particles. The color agent for a road marking material, contains no harmful elements and exhibits excellent tinting strength, hiding power, light resistance and heat resistance, and is suppressed in surface activity thereof. The road marking material using the color agent, shows a less change in hue with the passage of time and an excellent retroreflective property.
