BLACK PIGMENT FOR REFLECTING INFRARED LIGHT, AND PAINT AND RESIN COMPOSITION COMPRISING THE PIGMENT FOR REFLECTING INFRARED LIGHT

摘要

PPROBLEM TO BE SOLVED: To provide a black pigment for reflecting an infrared light which contains no harmful element and from which a heat shielding paint having excellent infrared light reflecting properties can be obtained. PSOLUTION: This black pigment for reflecting an infrared light comprises a complex oxide containing Fe, Co and at least one metal selected from the group consisting of Mg, Ca, Sr, Ba, Ti, Zn and Cu and has an average plate-surface diameter of 0.02 to 5.0 m and its particle form is the form of a plate, wherein the average reflectivity of the pigment at a wavelength in the range of from 250 to 780 nm in a visible light region is 10% or less and the average reflectivity of the pigment at a wavelength in the range of from 780 to 2,500 nm in a infrared light region is 35% or more.
