Abstract
The invention relates to a colored, multi-layered composition having a high level of Total Solar Reflectance (TSR). The composition includes a thin top, weatherable layer having a minimal amount of colored pigment suitable for optical hiding. In one embodiment a pigmented topcoat having less than 12 percent colored (non-white) pigment in a KYNAR AQUATEC emulsion (Arkema Inc.) is placed over a white elastomeric acrylic primer on a substrate to produce a colored multiplayer composition with a TSR of greater than 70%.
