DISPERSION OF SLIGHTLY SOLUBLE COMPOUND AND METHOD FOR MANUFACTURING THE SAME, RECORDING LIQUID USING THE SAME, INK SET, PRINTED MATTER, IMAGE FORMATION METHOD, AND IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a dispersion in which primary particles of a slightly soluble organic compound or a water insoluble color material having a fine nanometer size are incorporated as columnar particles having a prescribed shape and to provide a method for manufacturing the dispersion, to provide a dispersion having high dispersion stability and shelf stability, capable of being stored for a long time maintaining desired performance and containing the columnar fine particles and to provide a manufacturing method for efficiently obtaining the dispersion.;SOLUTION: In the slightly soluble organic compound dispersion containing the fine particles of the slightly soluble organic compound, the columnar particles have an aspect ratio of 3 or more, 50 to 300 nm major axis length and ≤50 nm volume average particle diameter measured by dynamic light scattering measurement of 0.5 mass% liquid.;COPYRIGHT: (C)2010,JPO&INPIT
