Abstract
A process for dyeing and printing cellulose-containing textile material, wherein the dye used is a compound of the general formula I ##STR1## where K is the radical of a coupling component of the pyridone, pyrazole or indole series, one of the radicals X, Y and Z is a carboxylic acid ester group of a total of 2 to 19 carbon atoms, a carboxamide group of a total of 1 to 19 carbon atoms, an unsubstituted or substituted sulfonic acid phenyl ester group or a sulfonamide group of a total of 6 to 18 carbon atoms, and the remaining substituents X, Y and Z are hydrogen, methyl, chlorine, bromine or nitro.
Claims7
A process for dyeing and printing water-swellable cellulosic materials and blends thereof with synthetic materials in the presence of water and a solvent that is capable of maintaining cellulose in the swollen state, wherein the dye used is a compound of the general formula:
- ##STR144## wherein B is an alkyl group containing from 8 to 18 carbon atoms,
- R is hydrogen or an alkyl group containing from 3 to 7 carbon atoms, and
- T is hydrogen, cyano, carbamyl or acetyl.
