Abstract:
1. A method for manufacturing a dispersion, including a dispersion medium and particles dispersed therein, which particles are formed from a reaction product by allowing at least two types of liquids to react with each other, said method comprising the following steps: preparing at least two nozzles, the openings of which have a diameter of 500 μm or less; and ejecting at least two types of liquids from the independently provided respective nozzles so that traveling directions of the liquids intersect with each other at an angle of 120° or less and so that the liquids then flow in an integrated manner to come into contact with each other to give rise to the reaction product, wherein one of the ejected liquids is a solution containing a pigment, and another of the ejected liquids is a solvent decreasing the solubility of the pigment, and at least one of the liquids contains a dispersing agent, and wherein the flow rates of the ejected liquids are each set so that L/S is in the range of 26 to 360, in which a nozzle opening area and a flow rate of an ejected liquid are represented by S (mm
