Abstract

A composite material including a black pigment and a textile material. The composite material has a reflectivity toward near infrared electromagnetic radiation having a wavelength from 800 nm to 2500 nm of greater than or equal to 12%, and has a reflectivity toward visible light having a wavelength from 350 nm to 750 nm of less than or equal to 10%. The composite material also has a blackness (M y ) from 125 to 165.
