Abstract:
The object of the present invention is to provide a method of producing organic pigment microparticles which can surely suppress growth and/or aggregation of particles. The present invention provides a method of producing organic pigment microparticles, comprising the following steps: Step 1 of precipitating organic pigment microparticles by mixing an organic pigment raw material liquid in which an organic pigment raw material is mixed with a solvent, and a precipitation solvent for precipitating the organic pigment microparticles from the organic pigment raw material liquid in a thin film fluid formed by introducing the organic pigment raw material liquid and the precipitation solvent in the space between at least two processing surfaces which are disposed so as to face each other, being capable of approaching to and separating from each other, at least one of which rotates relatively to the other; and Step 2 of coating at least a part of the organic pigment microparticles with an oxide coating; wherein the oxide coating is optically colorless and transparent, and Step 1 and Step 2 are performed out continuously in the thin film fluid, or Step 2 is completed at a predetermined time after Step 1 until the organic pigment microparticles grow and/or aggregate.

Claim (Index 14):
The method for producing organic pigment microparticles according to  claim 12 ,\n wherein the first fluid, the second fluid and the third fluid are used; the first fluid contains the precipitation solvent, the second fluid contains the organic pigment raw material liquid and a substance for treating the oxide coating raw material, and the third fluid contains the oxide coating raw material and the coupling agent; the central side of the at least two processing surfaces is the upstream side and the outside is the downstream side; the first fluid passes between the at least two processing surfaces from the upstream side to the downstream side while forming the thin film fluid; the second fluid passes through the second flow path independent of the first flow path into which the first fluid is introduced between the at least two processing surfaces, and is introduced into the space between the at least two processing surfaces from an opening formed on at least one of the at least two processing surfaces, and the organic pigment raw material liquid and the precipitation solvent are mixed between the at least two processing surfaces to precipitate the organic pigment microparticles; the third fluid passes through the third flow path independent of the first flow path and the second flow path, and is introduced into the space between the at least two processing surfaces from an opening formed on at least one of the at least two processing surfaces; the opening of the second flow path is located upstream of the opening of the third flow path; and the thin film fluid containing the precipitated organic pigment microparticles and the third fluid are mixed between the at least two processing surfaces, so that the oxide coating raw material reacts, and at least a part of the organic pigment microparticles in the thin film fluid is coated with the oxide coating.
