Procedure

If the tetrazonium salt solution of 2,7-diaminocarbazole which has been described is coupled one-sided to 7-(2,4-diamino-5-sulphophenylazo)-1-hydroxy-naphthalene-3-sulphonic acid and subsequently to phenol, ortho- or meta-cresol, resorcinol, 1,3-diamino-benzene or 1,3-diaminobenzene-4-sulphonic acid, dyestuffs of black shades are obtained.
