Colored fluids for electrowetting, electro fluidic, or electrophoretic devices, and the devices themselves, are disclosed. The colored fluid can include a nonaqueous polar solvent having (a) a dynamic viscosity of 0.1 cP to 50 cP at 250 C, (b) a surface tension of 25 dynes/cm to 55 dynes/cm at 250 C, and (c) an electrowetting relative response of 40% to 80%. Such colored fluids further include a colorant selected from a pigment and/or a dye. In another embodiment, the colored fluid can include a non-polar solvent and an organic colorant selected from a pigment and/or a dye. Such colored fluids can be black in color and have a conductivity from 0 pS/cm to 5 pS/cm and a dielectric constant less than 3. The use of the colored fluids offers improvements in reliability, higher levels of chroma in the dispersed state, and the ability to achieve higher contrast ratios in display technologies.

Colored fluids for electrowetting, electrofluidic, and electrophoretic technologies

Colored metalorganic fluids for electrowetting, electrofluidic, and electrophoretic devices are disclosed. The colored fluid can include a polar or nonpolar solvent including silicon and/or germanium and a modified, oligomeric, or polymeric dye. The dye includes a chromophore attached to a low molecular weight group with molecular weight 10 to 800 or an oligomeric or polymeric chain, which includes silicon and/or germanium. The dye has a molecular weight from 100 to 100,000, solubility in the solvent of at least 5% wt at 25&#xb0; C., and a dynamic viscosity from 0.5 cPs to 2,000 cPs at 25&#xb0; C. If the solvent is polar, the fluid has a conductivity from about 0.01 pS/cm to 3000 pS/cm, a surface tension of 15 dynes/cm to 90 dynes/cm at 25&#xb0; C., and a total content of monatomic ions with radii smaller than 2.0 A and polyatomic ions with radii smaller than 1.45 A less than 500 ppm.

Colorants for metalorganic compounds and their application in electronic display technology

Colored conductive fluids for electrowetting or electrofluidic devices, and the devices themselves, are disclosed. The colored conductive fluid includes a polar solvent and a colorant selected from a pigment and/or a dye. The polar solvent has (a) a dynamic viscosity of 0.1 cP to 1000 cP at 25&#xb0; C., (b) a surface tension of 25 dynes/cm to 90 dynes/cm at 25&#xb0; C., and (c) an electrowetting relative response of 20% to 80%. The colored conductive fluid itself can have an electrical conductivity from 0.1 &#x3bc;S/cm to 3,000 &#x3bc;S/cm and can have no greater than 500 total ppm of monatomic ions with ionic radii smaller than 2.0 &#x212b; and polyatomic ions with ionic radii smaller than 1.45 &#x212b;. The colored conductive fluid should not cause electrical breakdown of a dielectric in the device in which it is employed. An agent for controlling electrical conductivity can optionally be added to the colored conductive fluid.

Colored conductive fluids for electrowetting and electrofluidic technologies

A sulfonated derivative of an organic pigment moiety comprising a polyetheramine, and a metal or ammonium salt. The pigment is used for coloration of printing inks and coatings. For ink-jet systems there is excellent filterability, low viscosity, and stability thereof.

Pigments for non-aqueous inks and coatings

Phthalocyanine blue pigments and pigment dispersions for water-borne inks and coatings are described. The pigments are produced by dry milling phthalocyanine blue and a polymeric dispersant, optionally with inorganic fillers and other additives, to obtain a material with improved coloristic, rheological, and stability properties. The resulting activated crude is then processed directly into water-based pigment dispersion with additives and/or surfactants to facilitate conversion to pigmentary form while maintaining the desirable green and clean shade.

Copper phthalocyanine blue pigment composition and water borne dispersion thereof

A pigment's etheramine sulfonic acid salt is described. Also described is a method for enhancing the performance of a pigment composition containing an organic pigment, comprising enhancing the dispersion of said pigment by adding to 100 parts of said pigment about 1 to 40 parts of a pigment's etheramine sulfonic acid salt.

Treatment of high performance pigments

An etheramine pigment dispersing salt for enhancing the dispersion performance of an organic pigment composition adding to 100 parts by weight of pigment about 1 to 40 parts by weight of an etheramine pigment dispersing salt.
