Abstract

A procedure for preparing a stable and concentrated diazo-urea dye solution, characterized in that phosgene is reacted with an aqueous solution of an alkanolamine salt of an aminoazo compound of the formula EAN = NB-Nh2, alone or mixed with 50 mol%, at most, of an aminoazo compound of the formula E'' - A'' - N = N-B'' -NH2, at a temperature of 35ºC to 60ºC, while maintaining the pH of the reaction solution at a range of 5.0 to 8.5 by means of a lithium base, alone or in combination with at most 35% triethanolamine, N-methyldiethanolamine or N, N-dimethiethanolamine, representing in the aminoazo compound ** Formula ** each independently, a naphtylene or phenylene group, unsubstituted except for E and E'' or subsequently substituted by one or two groups of which one is taken from the group consisting of hydroxyl, nitro, cyano, trifluoromethyl, carboxyl and SO3M (where M is K, Ma, Li or H) and/or one or two are taken from the set consisting of al lower chyle, lower alkoxy, hydroxy-lower alkyl, hydroxyl-lower alkoxy and halogen.
