BLACK COMPOUND OXIDE PARTICLE/POWDER HAVING ABILITY TO REFLECT INFRARED LIGHT AND ITS MANUFACTURING METHOD, AND BLACK PIGMENT, AND PAINT AND RESIN COMPOSITION USING BLACK PIGMENT HAVING ABILITY TO REFLECT INFRARED LIGHT

摘要

PPROBLEM TO BE SOLVED: To provide a black pigment having ability to reflect infrared light, in which a harmful element is not contained and from which heat shielding paint having excellent infrared reflection property can be obtained. PSOLUTION: The black pigment having the ability to reflect infrared light is composed of a compound oxide containing Fe, Co, Al and further one or more metals selected from Li, Mg, Ca, Sr, Ba, Ti, Mn, Zn, Sn, Zr, Si and Cu and has 0.02-5.0 m average particle size. The average reflectance in the visible light region wavelength of 380-780 nm is 10% and that in the infrared light region wavelength of 780-2,500 nm is 30%. PCOPYRIGHT: (C)2008,JPO&INPIT
