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.

Abstract: A colored fluid for use in a display device comprises at least one first pigment, at least one non-polar solvent, and at least one polymeric dispersant comprising the formula: (Z-U)x-P-(V-W)y. P is a residue of a second pigment, which may be the same or different from the first pigment. Each Z is independently a non-polar polymer. Each U and V are various linking groups. Each W is independently selected from H, OH, SH, alkyl, aryl, alkylaryl, ammonium, alkylammonium, arylammonium, alkali metal, and alkaline earth metal. Each V-W bond is a covalent or ionic bond, x is an integer greater than or equal to 1, and y is an integer greater than or equal to 1, and wherein for the colored fluid, at least one polymeric dispersant comprises an ionic (V-W) moiety.
