The present invention provides a colored solar reflective system comprising (1) a particulate material having a substantially rutile crystal habit and having an average particle size of between about 0.5 µm and about 2.0 µm and (2) an organic pigment having a maximum absorption coefficient of about 5,000 mm-1 or greater in the visible light region, a maximum scattering coefficient of about 500 mm-1 or less in the visible light region and an average absorption coefficient of about 50 mm-1 or less in the infrared region.. The solar reflective system, which may be used in a coating composition or as a composition from which articles can be formed, exhibits a dark, intense color while also providing enhanced total solar reflectance. |
