摘要: For dyeing and printing cellulose fibers swollen with water-miscible swelling agents or fibre blends containing these fibres, the fibres are treated with dyestuffs of the general formula ##STR1## wherein R.sub.1 represents aryl,R.sub.2 represents halogen, CN, CF.sub.3, NO.sub.2, Q.sub.1, --OQ.sub.1, --COOQ.sub.1, CONQ.sub.1 Q.sub.2 or --NHCOQ.sub.1,R.sub.3 represents H, halogen, CN, CF.sub.3, Q.sub.1 or --OQ.sub.1 andK represents the radical of a coupling component,whereinQ.sub.1 denotes alkyl or aryl andQ.sub.2 denotes hydrogen, alkyl or aralkyl,and the dyestuffs are fixed by heat treatment.
