Abstract
The invention provides a layered colored solar reflective system comprising (i) a first layer comprising a first particulate material having a substantially rutile crystal habit and an average particle size within a range of about 0.55 μm and about 0.95 μm, dispersed in a vehicle and (ii) a second layer positioned on at least a portion of the first layer, the second layer comprising a second particulate material having a substantially rutile crystal habit and an average particle size within a range of about 1.0 μm and 1.6 μm, and a colorant dispersed in a vehicle. The layered color solar reflective system may be applied onto a structure to provide a dark, intense color as well as enhanced total solar reflectance.
