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.

Pigments for filtering the solar spectrum

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)-P-(V-W). 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.

Colored fluids for display devices

The present invention describes a pigment dispersion and a printing ink and coating employing the pigment dispersion. The pigment dispersion includes a pigment, binder and solvent. The pigment dispersion has a mean particle size less than about 120 nm. The printing ink or coating includes the pigment dispersion in addition to a solvent. The printing ink or coating has a solid binder to pigment ratio greater than about 1.5.

Pigment dispersions and printing inks with improved coloristic properties

The present invention provides a reversible piezochromic system that changes appearance upon application of a mechanical force. The reversible piezochromic system includes a cavity defined by a first substrate and a second substrate. The cavity includes at least a first fluid. The first fluid spreads when a mechanical force is applied to the system. The relaxation time of the first fluid depends upon the internal forces of the system. These internal forces at least include the surface energy differences between the substrates and the fluid or fluids, and the rheological properties of the fluid or fluids.
