Abstract

PURPOSE: A highly concentrated orange- or red-colored dye aqueous solution useful for dyeing cellulose, etc., having extremely higher water-solubility than that of a sodium salt and improved storage stability, obtained by converting an acid group of a specific disazo dye into a hydroxyethylamine salt.
CONSTITUTION: For example, a 10W40wt% highly concentrated aqueous solution of a disazo dye shown by the formula I (X and Y are benzene or naphthalene nucleus residue; M is a group shown by the formulae II, III, IV, or Na; m and n are 1W2; Z is residue of alkylamine, alkanolamine, heterocyclic amine, or aromatic amine). To obtain the dye, for example, a diazo compound is diazotized and subjected to alkali coupling in the presence of a triethanolamine salt of aminonaphthol sulfonic acid and triethanolamine to form a monoazo dye, which is condensed with a cyanuric halide while its pH being adjusted with triethanol amine, and finally condensed with an alkylamine, etc.
USE: Dyeing polyamide, leather, etc., ink for signature pen, etc.
