ABSTRACT:
A water-soluble monoazo-dyestuff of the formula ##STR1## WHEREIN R represents lower alkyl or lower alkoxy, R' represents hydrogen, lower alkyl or lower alkoxy, X represents --SO.sub.2 --CH.sub.2 --CH.sub.2 --OH, --SO.sub.2 --CH.sub.2 --CH.sub.2 --O--SO.sub.3 H, --SO.sub.2 --CH.sub.2 --CH.sub.2 --O--PO.sub.3 H.sub.2, --SO.sub.2 --CH.sub.2 --CH.sub.2 --S--SO.sub.3 H or --SO.sub.2 --CH.sub.2 --CH.sub.2 --N (lower alkyl).sub.2, and n stands for the integer 1, 2 or 3 said dyestuffs being suitable for the dyeing or printing of nitrogen containing native or synthetic fibrous materials and particularly of native or regenerated cellulose fibres with high tinctorial strength, the dyeings and prints obtained on the cellulose fibres being distinguished by considerable fastness properties to wear, to processing and to use. Padded or printed on cotton and fixed by different methods well known in the art, the novel dyestuffs yield prints or dyeings having the same clear shade that means they possess a very good constancy of shade in the use of different fixation processes. Used in printing processes they yield prints with sharp outlines.
