摘要：
A method for producing a liquid composition containing pigment particles is provided including (1) maintaining a mixture of a solvent and pigments of at least two types including a pigment A insoluble in the solvent at a normal temperature and a normal pressure, and a pigment B soluble in the solvent at the normal temperature and the normal pressure, at a temperature exceeding the normal temperature and a pressure exceeding the normal pressure, thereby obtaining a pigment solution in which the pigment A and the pigment B are dissolved; and (2) cooling the pigment solution to a temperature precipitating a deposition of the pigment A or lower, thereby precipitating pigment particles containing the pigment A and the pigment B.
