Abstract
The present invention relates to IR reflective black pigment compositions comprising a halogenated copper phthalocyanine such as C.I. Pigment Green 7 and a perylenetetracarboxylic acid diimide such as C.I. Pigment Violet 29. The compositions are characterized by an IR reflection spectrum with a positive slope in the wavelength range between 800 and 900 nm when incorporated as coloring agents in coatings or plastics. The inventive IR reflective black pigment compositions are useful for coloring high molecular weight materials like coatings, inks and plastics.
