Abstract: A method of producing organic particles, which contains dissolving an organic material into a good solvent to form a solution, and mixing the solution with a poor solvent for the organic material, in which the poor solvent is compatible with the good solvent, to form particles of the organic material in a liquid mixture, in which at least one selected from the group consisting of an anionic surfactant having 14 or more carbon atoms (dispersing agent A) and a specific compound having an azo group (dispersing agent B) is contained in the liquid mixture in which the organic particles are formed.
Abstract: Two or more solutions comprising an organic pigment solution in which an organic pigment is dissolved in a good solvent, and a poor solvent compatible with the good solvent, or a solution of the poor solvent are allowed to flow through a microchannel in a non-laminar state; and organic pigment fine particles are deposited from the organic pigment solution in a course of flowing through the microchannel by changing the solubility of the organic pigment solution with the poor solvent or the solution of the poor solvent. As a result, nanometer-scale monodisperse organic pigment fine particles can be produced in a stable manner.
Abstract: A method of modifying a pigment that includes reacting a reactive compound having an X-[Y]n reactive group with a secondary compound N-S-ZM to form a substituted reactive intermediate [Y]a-X-(N-S-ZM)b.

Abstract: Crude indanthrone is milled, with or without other additives, to reduce and normalize particle size and distribution to a sub-pigmentary, near amorphous, state. The resulting highly aggregated crude powder is then treated with a heterogeneous solvent system of water and an alkyl ester of an aromatic carboxylic acid, such as methyl benzoate, to de-aggregate and grow the particles back to a pigmentary size. The conditions of the solvent treatment can be controlled with respect to temperature, time, and solvent ratio such that the desired properties of strength, shade, and dispersability are optimized.
Abstract: A process for the preparation of pigment compositions which give improved ink flow is provided which comprises treating the pigment, during the pigment synthesis, with a small amount of a long chain aliphatic amine. The pigment compositions obtained can be used for preparing millbase inks which due to their improved flow viscosity (rheology) at high pigmentation can be easily handled as well as flexibly formulated, e.g. a number of final printing inks for different ink applications can be manufactured from a single millbase in a very economical manner. The final inks are preferably used in packaging gravure printing processes.
