| titleOfInvention | Method for producing highly concentrated aqueous solution of cationic azo dye |
| abstract | (57) [Summary] (Modified) [Structure] (a) In a solution containing sulfuric acid, an amine of D-NH 2 (1) is diazotized, and (b) this diazonium salt is converted into a compound of the formula (2). Coupling to the coupling component, (C) treating the produced azo dye with a water-soluble hydrogen carbonate, and (d) converting the dye hydrogen carbonate into a dye salt of the acid using an organic acid. , For example And a method for producing a high-concentration aqueous solution of a salt of a cationic azo dye. [Effect] This dye solution has excellent storage stability. That is, crystals do not precipitate even when stored at low temperature for several months. These solutions are essentially free of hydrochloride and do not corrode in conventional equipment. |
