ULTRAVIOLET LIGHT SCREENING COMPLEX FINE PARTICLE

摘要

PROBLEM TO BE SOLVED: To obtain ultraviolet light-screening complex fine particles capable of controlling ultraviolet light screening abilities and visible light transparency in a wide range. SOLUTION: The ultraviolet light-screening complex fine particles are complex fine particles obtained by combining large particles composed of inorganic particles having 0.1-5.0μm average particle diameter of primary particles, 2.7-4.0 band gap energy eV and ultraviolet light-screening abilities with small particles composed of inorganic particles having 0.001-0.1μm average particle diameter of primary particles.
