Abstract
A hybrid pigment composition is provided including a pigment or a dye and a fibrous clay. The pigment composition has higher reflectance in a near infrared region than a visible light region of the electromagnetic spectrum. The fibrous clay can be selected from palygorskite, sepiolite, and mixtures thereof. The hybrid pigment composition is tunable to provide high reflectance at a desired wavelength in the near infrared region.
