摘要：
A water-soluble monoazodye having the following formula (I) in its free acid form: ##STR1## wherein X is --CH.dbd.CH.sub.2 or --CH.sub.2 CH.sub.2 W wherein W is a leaving group removable by alkali; R.sup.1 is methyl, --NHCONH.sub.2 or --NHCOT.sup.1 wherein T.sup.1 is methyl, ethyl, --CH.sub.2 CH.sub.2 COOH or --CH.dbd.CHCOOH; R.sup.2 is hydrogen, lower alkyl or lower alkoxy;and Z is ##STR2## wherein P is cyano or halogen, each of Q and U which are independent of each other, is halogen, V is halogen or ##STR3## and Y is halogen or a group of the following formula (1) or (2): ##STR4## wherein R.sup.3, A, R.sup.4 and E are as defined in the disclosure and G is as defined above, has a moderate yellow to orange color and is particularly suitable for dyeing cellulose fibers or nitrogen-containing fibers.
