Abstract
The present technology relates to a transparent coating system or film which comprises a transparent, polymeric material, one or more pearlescent pigments, and one or more transparent dyes, organic pigments, organic pigment derivatives or inorganic pigments. The coating may be used to give well-defined transmission and reflection spectra in the visible region while having a high degree of reflection in the NIR region.
