Abstract
A coating composition comprising 6 to 20 alternating layers of SiO2 and one of ZrO2 or Nb2O5 wherein the thickness of each individual layer is about 70 nm to 200 nm is described. Also described is a substrate comprising a coating on at least a first major side thereof, the coating comprising 6 to 20 alternating layers of SiO2 and one of ZrO2 or Nb2O5 wherein the thickness of each individual layer is about 70 nm to 200 nm. The substrate can be glass, plastic, or metal. Also disclosed herein are methods of making the coated substrate. The coatings have good optical transparency and NIR reflectivity.
