  • Patent number: 7329315
    Abstract: 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.

  • Patent number: 7282263
    Abstract: A method of coloring a cellulosic material which includes a) dispersing pulped cellulosic material into water; and b) coloring the pulped cellulosic material by adding a cationic dispersion to the water, where the dispersion includes: (i) at least one pigment; (ii) water; and (iii) at least one acid salt of a styrene maleimide resin in an amount effective to disperse the pigment. The cationic dispersion may be prepared by (i) mixing, at 500 to 10,000 rpm, at least one pigment; water; and either (a) at least one acid salt of a styrene maleimide imide resin or (b) at least one styrene maleimide imide resin in combination with at least one weak acid, thereby forming a dispersion premix; (ii) milling the dispersion premix in a mixer filled with ceramic, metal or glass beads for a period of time sufficient to reduce pigment agglomerates to primary particles, thereby forming a nonstandarized dispersion; and (iii) standardizing the dispersion against a color standard by adding water.

  • Patent number: 7252710
    Abstract: A pigment dispersion composition which can be suitably applied in such fields as color filters, black matrices and ink jet recording where it is necessary to finely disperse pigments still with retention of good dispersion stability and temporal stability even when the total amount a pigment derivative, pigment intermediate, colorant derivative and colorant intermediate, and/or a pigment dispersant is small. Another object is a pigment dispersion-based resist composition which can give color filters high in permeability, excellent in contrast and causing no bleeding or black matrices high in light-shielding and insulating properties, and causing no bleeding.
