摘要：
Provided is a method for producing a pigment, in particular, a metal phthalocyanine, in high yield and in a green process. The method has (1) a step of obtaining a solution mixture by mixing at least one type of compound serving as a raw material for a pigment with a solvent, and (2) a step of obtaining the pigment by reacting the compound while holding the solution mixture at not less than a temperature where a subcritical state or a supercritical state of the solvent occurs.
