    摘要： Nano-sized phthalocyanine pigment particles include a phthalocyanine chromogen structure as the main component, and a substituted soluble metal-phthalocyanine dye as a minor component that is associated non-covalently with the phthalocyanine chromogen structure, wherein the presence of one or more sterically bulky substituents on the substituted soluble metal-phthalocyanine dye limits an extent of pigment particle growth and aggregation, to afford nano-sized pigment particles.

    摘要： An electrophoretic particle salt that includes a cationic electrophoretic particle and an anionic group ionically associated with the cationic electrophoretic particle is employed in an electrophoretic display. A spacer group chemically bonds a cationic moiety to a surface of the electrophoretic particle. A method of making the electrophoretic particle salt includes particle surface modification, nucleophilic substitution to create an interim salt and anion exchange. The electrophoretic particle salt has an ionization constant that favors dissociation into a positively charged electrophoretic particle and the anionic group in a nonpolar medium. The electrophoretic display includes a pair of electrodes and a dispersion of the electrophoretic particle salt in a nonpolar medium in a gap between the pair of electrodes.

    摘要： A method for producing nanoscale organic solid particles is proposed, starting from the corresponding sublimable organic solid as raw material, in the form of particles having an average particle diameter in the range of from 1 μm to 10 mm, which are dispersed in a carrier gas so as to obtain a dispersion, which is relaxed in a convergent nozzle, which is followed by an expansion chamber, and wherein openings are provided rotationally symmetrically about the midaxis of the expansion chamber in the wall of the expansion chamber which comprises the product outlet opening, through which openings a secondary gas flow is injected comprising an inert gas carrier and molecules, ions or nanoscale particles contained in molecularly disperse form therein, which are different from the raw material and which have an average particle diameter that is less than the average particle diameter of the product.

    摘要： Nanoscale particles of benzimidazolone pigments are made by providing one or more organic pigment precursor(s) to a benzimidazolone pigment, providing a solution or suspension of a sterically bulky stabilizer compound that associates non-covalently with a benzimidazolone moiety on one of the pigment precursors, wherein the sterically bulky stabilizer compound is selected from the group consisting of substituted pyridine derivatives, alkylated benzimidazolone compounds, alkylated derivatives of aromatic acids, and mixtures thereof, and carrying out a coupling reaction to form a benzimidazolone pigment composition, whereby one or more functional moieties on the benzimidazolone pigment is non-covalently associated with the sterically bulky stabilizer, so as to limit an extent of particle growth and aggregation and results in nanoscale pigment particles.
