Abstract

PURPOSE: To obtain the titled reactive dye in a high yield, by reacting an azo dye having a sulfatoethylsulfonyl or vinylsulfonyl group, a sulfonic group and a copper complex salt-forming group with a copper-complexing agent in the presence of formic acid or a salt thereof at a specified pH.
CONSTITUTION: An aq. soln. of an azo dye such as one of the formula having a sulfatoethylsulfonyl or vinylsulfonyl group, a sulfonic group and a copper complex salt- forming group is adjusted to 3W7 in pH with successive addition of formic acid or a salt thereof, an alkali (or alkaline earth) metal salt, a copper-complexing agent such as copper sulfate, and an inorg. acid or base, and reacted with these added components at 20W105°C. After completion of the reaction, the reaction soln. is salted out with addition of NaCl, to obtain a copper complex salt-contg. reactive azo dye.
EFFECT: A highly soluble reactive dye giving a product dyed in dark color is obtd.
