A laminate has a composite coating on a substrate. The substrate is a polymeric substrate with a surface resistivity of 4×102 to 1×108Ω/□; or a textured substrate with surface features which are 100 nm to 10 microns high. The composite coating comprising a tie layer of a nickel-chromium alloy; a layer of a reflective metal; a layer of aluminum oxide; a layer of silicon oxide; and optionally a layer of indium tin oxide. The laminate has a solar absorbance at a wavelength of 0.25 microns to 2.5 microns of between 0.07 and 0.7; and the laminate has an IR emittance of 0.1 to 0.8. Solar absorbance and IR emittance of the laminate may be independently to control the ratio of solar absorbance to IR emittance. Solar absorbance may be adjusted by changing the surface resistance or degree of texturing on the substrate. IR emittance may be adjusted by changing oxide film thickness.
