<P>PROBLEM TO BE SOLVED: To provide a water-insoluble coloring material dispersion in which the primary particles of water-insoluble coloring material fine particles are extremely fine and which has high dispersion stability and very high storage stability and can be stored for a long period of time. <P>SOLUTION: There is provided the water-insoluble coloring material dispersion comprising the fine particles of the water-insoluble coloring material, an aqueous medium and a polymer, characterized in that the polymer is a polymer prepared by polymerizing a polymerizable compound having an acid group such as carboxylic acid group, sulfonic group, or the like and forming a hydrophilic site, a styrenic polymerizable compound which may have a substituent and forms a hydrophobic site, and a styrenic polymerizable compound represented by general formula (I) (wherein, the ring A is an N-containing heterocyclic group, and may further have a ring structure group on the heterocyclic group). <P>COPYRIGHT: (C)2010,JPO&INPIT |
