Claims (1)

Patent-Anspruch:Patent claim: Verfahren zur Darstellung von Farbstoffen durch Einwirkung der Diazoderivate der Sulfanilsäure, der m-Amidobenzolsulfosäure, der o- und p-Toluidinsulfosäure, der Xylidinsulfosäure und der Benzidin- und Tolidindisulfosäuren auf a-Naphtylamin, Diazotiren der so erhaltenen Körper und weitere Combination mit α- und β-Naphtol, sowie deren Mono- und Disulfosäuren. Process for the preparation of dyes by the action of the diazo derivatives of sulfanilic acid, the m-amidobenzenesulfonic acid, the o- and p-toluidinesulfonic acid, the xylidinsulfonic acid and of the benzidine and tolidinedisulphonic acids on a-naphthylamine, diazotires of the so obtained Body and further combination with α- and β-naphthol, as well as their mono- and disulfonic acids.
