Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a complex salt (I) without using NaCl. SOLUTION: A complex salt is precipitated when an aqueous solution, which is prepared by reacting a polyazo compound (II) with a copper salt and the like in the presence of water, is added in alcohol and the like. The complex salt (I) is obtained by filtering the precipitated complex salt. In the formula, Me is copper and the like, A is a naphthyl group having 1-3 substituents -SO3Q, Q is H and the like, and R1-R3are substituents. COPYRIGHT: (C)2010,JPO&INPIT
