Patent ID: 8177902

Claim:
A method for producing a liquid composition containing pigment particles, the method comprising: (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 (wherein the normal temperature means 25±15° C. and the normal pressure means 1.01325×10 5 ±0.01333×10 5 Pa) and a pigment B soluble in the solvent at the normal temperature and the normal pressure, at a temperature and a pressure of a super-critical state, 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 the pigment A or lower, thereby precipitating pigment particles containing the pigment A and the pigment B.
