Abstract

PURPOSE: To obtain monoazo dyes capable of dying securely and clearly synthetic fibers by the coupling reaction of a diazonium salt of 2-amino-5-nitrothiazoles, and a specific aniline in a dilute sulfuric acid in the presence of a nonionic surfactant.
CONSTITUTION: A diazonium salt of 2-amino-5-nitrothiazoles of the formula I (wherein X is H, a lower alkyl, or phenyl group) and an aniline of the formula II (wherein Y is H, a halogen, or a lower alkyl group, R1 and R2 are, a lower alkyl group, or phenyl group, and R3 is a lower alkyl group or phenyl group) are brought into a coupling reaction in a 1W45wt% aqueous sulfuric acid solution in the presence of a nonionic surfactant, e.g., an alkyl ester type, an alkyl ether type, or an alkyl aryl ether type, in order to obtain a monoazo dye of the formula III (wherein X, Y, and R1WR4 are the same as in the foregoing formulas).
