| titleOfInvention | PROCEDURE FOR THE PREPARATION OF AZOIC CA-TIONIC DYES. |
| abstract | Procedure for the preparation of cationic azo dyes, of the general formula I ** (See formula) ** in which A stands for an N-quaternized pyridine or quinoline system, which is linked in position 2, 3 or 4 to the quaternized nitrogen atom, R1 means an optionally substituted lower alkyl radical, a cycloalkyl radical or an optionally substituted aryl radical, R2 means a lower alkyl, alkoxy, alkoxycarbonyl or or carbamoyl group or a phenyl group, and Y- means the charge equivalent of an anion characterized in that the diazonium compound is coupled to a compound of a 2-, 3- or 4-amino-pyridinium salt or 2-, 3- or 4-aminoquinolinium N- quaternized, optionally further substituted with a 5-amino-pyrazole compound coupling in position 4, of formula II ** (See formula) ** in which R1 and R2 have the significance indicated under formula I, whose starting materials are chosen from those whose cationic particle of the final product does not show groups that dissociate acid in water.
