DISPERSION OF ORGANIC PIGMENT PARTICULATE MIXTURE, ITS SOLID MATTER AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a dispersion of mixed nanometer-sized organic pigment particulates, which has a narrow particle size distribution and shows a high light fastness, its solid matter and its production method, to provide the dispersion of the mixed organic pigment particulates, which has the excellent characteristics and can be suitably used for producing a color filter or an inkjet ink, and its solid matter, and to provide a production method for efficiently obtaining the dispersion.;SOLUTION: The dispersion of the mixed organic pigment particulates comprises at least two organic pigments as particle components, provided that the mixed particulates are nanometer-sized built-up pigment particulates which are produced through precipitation induced by contacting an aqueous medium with a mixed organic pigment solution wherein the at least two organic pigments are dissolved.;COPYRIGHT: (C)2008,JPO&INPIT
