Abstract
Disclosed are compositions that can be used in forming products with increased near infrared (IR) reflective capability. A composition can include IR reflective and/or IR transmissive non-white pigments and can be formed with suitable viscosity so as to successfully coat substrates, e.g., yarns, suitable for use in forming coverings for architectural openings, e.g., window coverings. Also disclosed are textile substrates coated with the compositions, including textile substrates coated with compositions that in dude abrasive, inorganic IR reflective dark pigments.
