Abstract
A method of producing fine particles of metal complex pigment, containing the step of reacting a solution of an alkali metal salt of a ligand that constitutes the metal complex with a solution of salts of a metal that constitutes the metal complex, in the course of a laminar flow in a channel; and a method of producing fine particles of metal complex pigment, containing the step of bringing a solution of an alkali metal salt of a ligand that constitutes the metal complex and a solution of salts of a metal that constitutes the metal complex into contact with each other in a channel having an equivalent diameter of 1 mm or less to form a liquid flow.
