Non-aqueous pigment dispersions exhibit improved dispersion quality and/or stability for a specific selection of quinacridone pigments, diketopyrrolo-pyrrole pigments and azo pigments by using specific naphthol AS dispersion synergists. The non-aqueous pigment dispersions can be advantageously used in inkjet inks inkjet printing methods.

A dry flushed pigment comprises a dry pigment and a flushing agent. Particles of the dry pigment are dispersed into the flushing agent. The dry flushed pigment may have at least 20 percent by weight dry pigment. The dry flushed pigment may have a range of 20 to 80 percent dry pigment by weight. A pigment concentrate comprising a dry flushed pigment and one or more of a group of an ink carrier, a dispersant, or a synergist, where the dry flushed pigment is mixed with one or more of the ink carrier, dispersant or synergist and then milled to create the pigment concentrate. The pigment in the pigment concentrate has a Z-average particle size in the range of 75 nm to 250 nm. The pigment in the pigment concentrates is present in the amount from about 15 to 60 percent by weight of the pigment concentrate.

摘要:
The present invention provides a macromolecular dispersant and a synthesis method thereof, and the dispersant is synthesized by reacting polyisobutylene-g-succinic anhydride with amine compounds. In addition, the present invention also provides an oil-soluble dispersant composition with nano particle pigments and the manufacturing method thereof. The oil-soluble dispersant composition is manufactured by milling a macromolecular dispersant with a pigment and a grinding media. The oil-soluble dispersant composition is adequate for various pigments, shows the excellent immiscibility of oil/water interface, and owns the low viscosity of ≦4 cps and the optical density of ink ≧1.1. Therefore, the oil-soluble dispersant of the present invention for the nano particle pigment can be acted as the material of the electrowetting display.

A colored curable composition for a solid-state image sensor comprises a polyhalogenated zinc phthalocyanine pigment, and a compound having at least a structure represented by the following Formula (A). In Formula (A), X1, X2, X3, X4, X5, and X6 each independently represent a substituent selected from —OH, —OR, or —NHCOCH═CH2, R represents a monovalent organic group. When the compound is an oligomer, the oligomer has a configuration in which at least one of X1, X2, X3, X4, X5, and X6 in a structure represented by Formula (A) is eliminated to form a single bond, which is then linked, via —O—, to another structure represented by Formula (A).

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.

摘要:
Reaction products of polyepoxides with amines followed by reaction with polyalkyleneoxide modified and/or polyester-modified and/or polyether-polyester-modified isocyanates give comblike aminic polymers, and their salts. The compounds are useful as wetting and dispersing agents for organic and inorganic pigments, and as fillers for aqueous and solvent-borne systems.
