Title (EN) PREPARATION OF CATIONIC AZO COMPOUNDS
(FR) PRÉPARATION DE COMPOSÉS AZOÏQUE CATIONIQUES
Abstract:
(EN) The present invention relates to a novel method for preparing cationic azo compounds, which preferably can be used as dyes. Further, the invention relates to novel cationic azo compounds and the use of N2O in the synthesis of azo-imidazolium dyes.
(FR) La présente invention concerne un nouveau procédé de préparation de composés azoïques cationiques, qui peuvent de préférence être utilisés comme colorants. En outre, l'invention concerne de nouveaux composés azoïques cationiques ainsi que l'utilisation de N2O pour la synthèse de colorants azo-imidazolium.
