Abstract

Procedure for the preparation of tetrakisazoic pigments, of the formula ** (See formula) ** where A, R1 and R2 signify a benzene or naphthalene radical, suitable for pigmentation of high molecular weight organic material, characterized by coupling, in the molar ratio of 2: 1, a diazo or diazoamine compound of an amine of the formula R1-N = N-R2-NH2 with a bis-acetoacetylamine derivative of the formula CH3COCH2CONH-A-NHCO CH2COCH3 in whose formulas the substituents have the same meaning expressed above.
