A near-infrared reflecting composite pigment comprises a near-infrared non-absorbing colorant and a white pigment coated with the near-infrared non-absorbing pigment. The near-infrared reflecting composite pigment can be produced by mixing a colorant dispersion, in which the near-infrared non-absorbing colorant is dispersed in a liquid medium, with the white pigment in a form selected from powder or a dispersion and then drying the resultant mixture. A near-infrared reflecting coating agent comprises as a coloring agent the near-infrared reflecting composite pigment. A near-infrared reflecting material comprises a base material coated on a surface thereof with the near-infrared reflecting coating agent.
近红外反射复合颜料由近红外非吸收着色剂和涂有近红外非吸收颜料的白色颜料组成。近红外反射复合颜料可以通过将着色剂分散体(其中近红外非吸收着色剂分散在液体介质中)与白色颜料(其形式可以选择粉末或分散体)混合,然后干燥所得混合物而制成。近红外反射涂层剂包括作为着色剂的近红外反射复合颜料。近红外反射材料包括表面涂有近红外反射涂层剂的基底材料。
