Abstract: PURPOSE: A method for producing fine organic pigment is provided to obtain a colored film with high transparency and excellent view-angle dependency. CONSTITUTION: A method for producing fine organic pigment comprises the steps of: obtaining a mixing composition by mixing organic pigment, water-soluble inorganic salt, water-soluble organic solvent, and resin; and removing water-soluble inorganic salt and water-soluble organic solvent in water. The resin has the solubility of 1 part by weight or more per 100 parts by weight of water-soluble organic solvent at 25°C. The resin has a group selected from an amino group and quaternary ammonium salt.
