An economical method for preparing metal compounds of an azo compound with a high space-time yield is provided to increase the reproducibility of the preparation of the metal compounds or host-guest compounds thereof, allow the reproducible formation of a product possessing a high BET surface area and minimize the fluctuation in product quality. The method for preparing metal compounds of an azo compound of the formula(1) or tautomeric structures thereof, which optionally contain a guest compound, is characterized in that the preparation is performed in a batch process using pumped circulation. In the formula(1), each rings labeled X and Y may carry one or two substituents selected from the group consisting of -O, -S, -NR7, -NR6R7, -OR6, -SR6, -COOR6, -CN, -CONR6R7, -SO2R8, alkyl, cycloalkyl, aryl and aralkyl(where R6 is H, alkyl, cycloalkyl, aryl or aralkyl, R7 is H, cyano, alkyl, cycloalkyl, aryl, aralkyl or acyl, and R8 is alkyl, cycloalkyl, aryl or aralkyl), the sum of the endocyclic and exocyclic double bonds for each of the rings X and Y being three, R1, R2, R3 and R4 are H, alkyl, cycloalkyl, aryl or aralkyl and additionally, as indicated in the formula(1) by the interrupted lines, may form 5- or 6-membered rings, to which further rings may be fused, R5 is -OH, -NR6R7, alkyl, cycloalkyl, aryl or aralkyl(where R6 and R7 are as defined above), and in the substituents given for R1 to R8 that contain CH groups, the hydrogen atoms in the CH groups may be substituted, and m, n, o and p may be 1 (one) or alternatively, where double bonds start from the ring nitrogen atoms on which the corresponding substituents R1 to R4 are located, as indicated in formula(1) by the dotted lines, may be 0. The metal compounds prepared by the method is used as a pigment for producing laminates, producing photoresists, producing of color filters in liquid-crystal displays or ink-jet printing.
