Claims (1)

Patent-Anspruch :Patent claim: 3030th 3535 4040 Abänderung des durch Patent 220722 geschützten Verfahrens zur Darstellung von sauren Wollfarbstoffen, darin bestehend, daß man anstatt der Diazoverbindungen von Ariiinoaryläthern der Benzol- oder Naphtalinreihe oder ihrer Homologen oder Substitutionsprodukte hier die Diazoverbindungen der Sulfosäuren der genannten Aminoaryläther mit sulfierten Phenylpyrazolonen oder ihren Substitutionsprodukten vereinigt.Modification of the method of representation protected by patent 220722 of acidic wool dyestuffs, consisting in the fact that one instead of the diazo compounds of aryinoaryl ethers of the benzene or naphthalene series or their homologues or Substitution products here are the diazo compounds of the sulfonic acids of the aminoaryl ethers mentioned with sulfated phenylpyrazolones or their substitution products combined.
