    摘要： Disclosed are pigment particles prepared by a process which comprises (a) preparing a solution of a polyalkylene oxide compound in water; (b) preparing a solution of a cationic dye in water; (c) admixing the solution containing the polyalkylene oxide compound with the solution containing the cationic dye to form a mixture; (d) adding to the mixture a solution containing a heteropolyacid in water, an alcohol, or a mixture thereof, thereby resulting in formation of pigment particles having an average particle diameter of no more than about 300 nanometers; and (e) after addition of the heteropolyacid to the mixture, neutralizing the mixture by addition of a base. Another embodiment of the present invention is directed to an ink composition comprising water and the aforementioned pigment particles.

    摘要： Disclosed is an ink composition which comprises water, an acid dye, a monovalent salt, a polyquaternary amine compound, and an optional nonionic or cationic surfactant, said ink being substantially free of organic solvents. The ink is particularly suitable for applications such as ink jet printing and marking pens. The disclosed inks in some embodiments are substantially indelible. Also disclosed is a composition for removing the ink compositions from substrates to which they have been applied which comprises water and a dianionic surfactant, optionally further containing a salt, urea, and/or a viscosity building agent such as a gum.

    摘要： A method of forming toner particles having surface particles attached thereto includes the steps of aggregating a material of at least one binder material and at least one colorant to produce toner particles, following aggregation, forming a mixture of the surface particles and the toner particles, and subjecting the mixture to a temperature above the glass transition temperature of the toner particles to coalesce the toner particles, whereby the surface particles become at least partially embedded within the surface of the toner particles. Toner particles prepared by such method include a core comprised of at least one binder and at least one colorant, and surface particles at an external surface of the toner particles, wherein at least about 50% of the surface particles are substantially completely covered by a portion of binder and a majority of the surface particles protrude from the toner particle surface a distance of at least 50% of the average particle size of the surface particles.
