Abstract

PURPOSE: To prepare a high-purity dis- or trisazo pigment efficiently, by reacting a tetra- or hexazonium salt with a specific coupling compound in the presence of an organic amine.
CONSTITUTION: A tetra- or hexazonium salt obtained by diazotation of an amino or diamino compound according to the conventional method is reacted with a coupling compound of formulas I, II, and III: (X and Ar1 are aromatic rings, e.g. benzene or naphthalene; heterocyclic rings, e.g. indole, carbazole, or benzofuran, or their substitution products; Ar2 and Ar3 are aromatic rings, e.g. benzene or naphthalene, or their substitution products; R1 and R3 are H, lower alkyl, phenyl, or their substitution products; R2 is lower alkyl, carboxyl or its ester) in a solvent in the presence of an organic amine, e.g. ethylamine or 1,2-diaminopropane, at -10 to 30°C for 5min to 3 hrs.
