Abstract

Textile material, consisting completely or partly of cellulosic material is dyed with water-insoluble azo-dyes, by treating the material with an aq. soln., pref. warm, contg. a reactive cpd. useful in the dyeing process, and an alkaline agent and an alkaline nitrite, then further treating the material thus impregnated, opt. after intermediate drying, with a second aq. bath at room temp. contg. an aq. dispersion of >=1 diazotisable amine suitable for the dyeing process and having a particle size =0.03 mm and an activating agent such as an acid to cause the formation of the azo-dye, opt. by means of heating and/or passing subsequently through a bath of NA2CO3. The reactive cpd. may be an acetic acid arylamide, a 2-hydroxy-napthalene carboxylic or heterocyclic ortho-hydroxycarboxylic arylamide e.g. 5-chloro-2-acetoacetylamino-1,4-diethoxy benzene. The alkaline agent may be an aq. metal hydroxide e.g. NaOH. The diazo cpd. is pref. a nitroaniline, aminosuphonic acid amide, amino-nitrile or benzoyl phenylene diamine. A dispersing agent of formula (I): R-O-Ar-CH2-AR-O(CH2CH2O)N-R (I) (where R is a 1-3 C alkyl, AR is arylene and n = 7-50) is opt. present. Strong, brilliant tints are obtd.
