    • PROBLEM TO BE SOLVED: To provide a method for producing a liquid dispersion of an organic pigment having a small size, wherein a particle size distribution peak is sharp and dispersion stability is excellent, to provide a method for producing a liquid dispersion of an organic pigment, wherein the steps from the production of organic pigment particles to the polymerization of a polymerizable compound can be conducted in one vessel and the above excellent liquid dispersion can be produced simply, easily and rapidly in a high purity state, and also to provide a method for producing organic pigment particles having excellent storage stability and dispersibility and their liquid dispersion, wherein the particle size of the organic pigment fine particles is homogeneous (monodispersed organic pigment fine particles) and the polymerizable compound is polymerized and fixed in a mixed solution. SOLUTION: The method comprises a process wherein a polymerizable compound is incorporated into at least one of an alkaline or acidic aqueous solution, wherein the organic pigment is dissolved, and an aqueous medium, the organic pigment is precipitated as fine particles in a process of mixing the both, and then, the polymerizable compound is polymerized, to thereby fix the polymer of the polymerizable compound to the pigment fine particles.
